secure sip trunk cucm driver

Hello

I have set up non-secure sip trunk using tcp of cucm to the driver

It's up on top of the cucm but in the driver call control is inaccessible

so the Conference made from an endpoint works but not the scheduled conference or composed auo

also, I set up a secure safe using tls

This time sip trunk is down in the side cucm and so it's on the driver side

I tried to download the temporary driver's certificate in the callmanager-trust and the tomcast-trust

Download the certificate of call manager to the conductor

but still does not work

I don't know if I need to generate a certificate authority certificates or just, I missed something?

CUCM: 10.5.2

conductor: XC4.0

Thank you

Hello

I recently deployed the CUCM and conductor (same version) as mentioned above.

My case was a little different as my certificate CUCM management was made by the internal certification authority, similarly to the conductor, I did the management of certificates, made sure the root certification authority is present in the two server to trust each other.

So I configured the location with port 5061 with ip address CM on the conductor.

Similarly on CM SIP trunk pointing to ad-hoc conductor and meeting woth port 5060 and security profile, device security mode an encrypted and the subject name X.509 to match the FQDN or Cluster COMPLETE domain name to match the domain the driver's FULL name, which allows the TLS communication code.

If I remember I was too faced the same problem when you face, however, after appropriate management of certificates and security profile, it has been resolved properly.

This guide should be useful

    Hello

    can you collect debug voice ccapi inout & debugging ccsip GCE message and attach the logs here please?

    your provider sends A Law G711 codec in the PROMPT message, but you have configured G711 U right in the dial-peers.

    can you try to fix G711 has the right dial-peers and check out them? Also make sure you have TPMS in the MRGL applied to CUCM SIP Trunk.

  • CUCM v8.5 with 3 SIP Trunks to the Lync Server - Route algorithm of Distribution for the Group

    I CUCM connected to three different Lync server via 3 different SIP trunks.

    RG is composed of the following elements:

    LYNC SIP TRUNK 1 (1.1.1.1)

    LYNC SIP TRUNK 2 (2.2.2.2)

    LYNC SIP TRUNK 3 (3.3.3.3)

    The route group was built with "Top Down" the algorithm of distribution. The first SIP trunk knows congestion and some calls are never routed to secondary and tertiary SIP trunks.

    Based on all the forum posts I've seen - it seems that I have to configure the algorithm of group distribution of ranges as 'circular '.

    If I change the algorithm group of "Circular" lines - can I expect the following results:

    1. first call will go through LYNC SIP TRUNK 1

    2. second call will cross LYNC SIP TRUNK 2

    3. third call will cross LYNC SIP TRUNK 3

    When I change the algorithm of distribution of the route to the 'circular' group and click 'SAVE', I am invited on "RESET".  This service assigns to the existing calls through SIP Trunks?

    TIA,

    Amir

    Hello

    the circular algorithm will work the way you mentioned, but I suggest to try and make sure that is not perform integration

    to reset the SIP trunk actually active calls should not be made because the gose media directly between endpoint unles syou use something like trust rely wher evous enforce calls to go to the SIP

    Therefore, in most cases is should be fine just try configuration at the time of the calls will face service disruption

    hope this helps

  • Problem with a SIP Trunk between VCS and CUCM

    Hello world

    I created a SIP Trunk between control VCS (X7.1) and a CUCM 8.6.

    I followed this Cisco_VCS_Cisco_Unified_Communications_Manager_Deployment_Guide_CUCM_6-1_7_8_and_X7 - 0.pdf deployment guide.

    The trunk is in place, but I have the following problem: I can ring since an EX90 recorded on the VCS for a registered on the CUCM 9951 but when I take the call, I have a busy signals (audio and video). When I on the EX90 9951 ring, I have the following message on VC: can not reach the contact.

    I have a 503 service unavailable status on the call history and "call rejected" on the event log.

    My transformation is OK and the call is sent to my neighbor CUCM zone

    You have an idea to solve this problem?

    Thanks for your help

    Best regards

    Bruno Z.

    Hello

    Yes, it's true! It seems at first glance a problem with codec negotiation when I see the reason 47 code.

    in any case set the region to G.711 trunk phone in case if you have different device pool and the trunk region and ip-phones.

    make G.711 end to end and test again.

    Thank you

  • is it possible, end point of video recorded in CUCM call standalon SX10 via SIP Trunk?

    Dear all,

    Need help :)

    1.

    is it possible, end point of video recorded in CUCM call standalon SX10 via SIP Trunk?

    my customers will not buy TP - lic :)

    Topology:

    8900 (jabber) - CUCM-(SIP) - SX10

    2.

    Customer, have MCU machine.

    If not possible. is it possible, meeting point of MCU use?

    Topology:

    8900 (jabber) - CUCM - MCU - SX10

    1. Yes, but it is not that simple and straightforward that the SX10 can be reached by calling is the public IP address and CUCM does not support the IP address numbering is not a SIP address format...

    2. Yes, using the MCU would be much simpler, easier and, in my opinion, a better solution to be implemented. Here is an example of how a stand-alone SX10 could dial the IP address of the MCU standard automatic.

    You can also assign a SIP URI address to the meeting point which the SX10 can connect to.

  • CUCM SIP-trunk multiple Ports

    I would like to know if it is possible to create a Script of SIP standardization in CUCM which change the Destination SIP port based on the phone which makes the phone.

    Current issue:

    The ITSP provider asked that I send calls from different regions to the same address IP SBC but a different port.

    Example:

    Phone (A) makes a call

    RP - RL - RG---> SIP Trunk (5060)---> CUBE (5060<-->5001)---> ITSP1

    Telephone (B) makes a call

    RP - RL - RG---> SIP Trunk (5060)--->---> CUBE ITSP1 (5060<-->5002)

    I can do it on the CUBE, but which require several dial-Exchange and SIP profiles, is it possible in the CUCM to change the sip by device-pool port?.

    Or is there another I can match and send calls via the same destination with different dial-peer sip ports.?

    Thank you.

    Zakiab,

    You can do this, its all just impossible. Your signage ports are defined not on the endpoints, but on the B2BUA (CUCM or CUBE). The CUBE, you have the most flexibility, because you can change the port of signs based on your dial-peers. However, as you pointed out quite rightly, need you an insurmountable amount of dial-peers to have this for each endpoint. So I suggest tell you your ITSP to change their design or moving to a new.

  • Sip Trunk design question

    Hello

    I have a requirement to pass an h323 to SIP environment environment. I'm looking for good practices, especially around security. I have 2 servers CUCM (8.5) in cities separated for redundancy. I have also 2 voice gateways which, at the present time, h323 to the PSTN, are each located in different cities.

    My requirements are:

    1. create a sip trunk instead of the supplier of the use of PRI.

    2 If the Wan link fails on a gateway provider, router replacing in the other location should be able to receive installation messages and if a user connects via extension mobility, should be able to answer the call.

    Is there a simplified design docos on for this? I hesitate to create a SIP trunk directly to the supplier for safety, thus thinking to end the call on the routers of voice with the CUBE. I am sure that it is managed from the factory and would appreciate comments.

    See you soon!

    Pieter

    Simple answer use ALWAYS the CUBE.  With IOS 15.1 T and more you have security against fraud free of charge that you can use to restrict which can address IP contacted the CUBE, that's all you need.

  • CallManager Express SIP trunk problem

    Hi all here.

    I have a problem with my SIP trunk CallManager Express (version 10.0). On my site already configured trunk SIP between CME and CUE. I have configured DN for SIP phone and SIP phones recorded on CME successfully, but... As soon as SIP phone registered on CME, DIAL-PEER for CME and CUE connection changes. Especially 'session target ipv4' automatically changes to my IP phone SIP and all calls go to my SIP phone and does not reach the auto attendant.

    How can I solve this problem?

    Hello

    Following is the error of CUCM;

    WARNING: 399 UnicompCM "cannot find a Device Manager for the request received on port 55549 leave 192.168.10.2.

    This probably means that CME use 192.168.10.2 for source packages SIP CUCM however SIP trunk in CUCM is not directed to this IP address, it is useful to point out to another IP interface of the GUY and therefore dismiss this appeal.

    Can you please check what is the IP of CMF address you configured on the SIP trunk in CUCM?

  • Configure (fxs) analog phones with Sip trunk

    Hi all

    IS - this configuration FXS possiple to knit on SIP TRUNK? I HAVE 16 FXS ports and voip gateway 2921 cisco.

    Configuring fxs to work with her?

    any help thanks.

    Is there a PBX at stake here, i.e. CUCM or CME?

    In both cases, you have set good dial-peers to point to the FXS ports to match the destination of the SIP trunk, which is pretty simple.

    It would be more accurate to say that the problem has been bypassed by using a transcoding resource. The correct resolution here would be to open a ticket to trouble with the ITSP. I agree that the PROMPT message you show doesn't include advertising RFC2833 in the SDP offer. It is a problem that only the carrier can rectify.

  • SIP trunk CUBE with Callcentric - incoming unanswered call

    I'm doing some tests with a Sip trunk with a provider called Callcentric.
    It is a CUBE scenario. I use a SIP to the CUCM trunk.

    Hello

    Please configure the sip requires low profile to remove the header and apply this profile in the dial-peer 1 outgoing.

    SIP-class voice profiles 1

    response header 200 sip requires DELETE

    If this does not work under Dial-peers, try to apply globally.

  • ISDN GW 3241 - security SIP

    Anyone know if this is in the roadmap an improvement on SIP/security settings in the ISDN GW 3241?

    We where to check the config and we couldn t find a way to configure the GW (version 2.2 (1.79) P to use SIP and avoid using non desired.)

    When the Dial Plan (IP ISDN) is configured as SIP or other, there is no configuration in the Don t Gulf war do not accept calls from any device that sends an INVITATION.  It takes a SIP trunk configuration, to make a relationship with her pair (only accept call form SIP trunk sources, certificates, etc.).

    Any idea?

    It is an impact on deployment of client (Government).

    Thank you

    Ok. Thanks for the answer (of course side would be also appreciated :-) of marking

    Not to mention that sometimes some information of the road map are mentioned here I would not wait or wait until it

    as this is a public forum, but the road map info is often under NDA.

    I recommend you talk to your partner about Cisco / contact and see if you can get a presentation of the road map

    and also note the impact for your deployments and possible feature requests for them.

    Hope that answered your question :-)

  • CME: assign extension sip trunk

    Hello

    Instead of using a prefix to use a separate sip trunk, I would like an IP phone to use a separate sip for its 2nd line trunk.

    Then I set up a 2nd line on an IP phone to use extention 96:

    ePhone 1
    Mac address *.
    name *.
    button 2:96

    ePhone-dn 96 double line
    Number of 432

    and then I would this extension (with the number ending in 432) always use a SIP server.

    I think I need a dial-peer to achieve this, similar to:

    Dial-peer voice voip 432
    destination-model?
    codec voice-class 1
    voice-class sip dtmf-relay rtp - nte force
    session protocol sipv2
    session target sip-Server
    DTMF-relay rtp - nte
    No vad

    How can I join the dial-peer name extension? (for analog, I would put "monitor trunk 1 * voice port number *"on the name extension ").

    Any help appreciated,

    Jonathan

    Hello.

    You can try with answer address under your dial-position 432 432.

  • SIP trunk behind a router using NAT

    Hello

    Is it possible to use a SIP trunk to a provider SIP ITSP having the CUBE / router gateway behind a firewall using a NAT?

    Does anyone do this?

    I ask because I'm having problems to make my SIP trunk to work and my router for cube is behind my generic service provider router, which makes the NAT. I just want to rule this out as a problem.

    Has anyone else done this? Or is it really impossible?

    Thank you very much

    Tom

    Hello

    As NAT works fine SIP would work properly as the Protocol.

    Here is the RFC for "NAT Traversal practices for Client - Server SIP"

  • Source IP address of the originating call to sip trunk

    I'm unable to set address ip source from trunk sip call. I read somewhere that the source ip address of the call must be the ip address that call device registered to. I also checked "run in all active nodes such as suggested by cisco. We have 3 Sub cluster and 1 pub however still call orgianate to a particular Sub.

    I also undergoes several changes i - e DP and list route but think not worked for me. Can someone help to sortout this problem?

    Let's say if your ip phone registered in sub - and "run on all nodes" enabled, then the source ip address is always sup - A s ip address regardless of the device pool config on the sip trunk.

    Could please explain you the device pool config in phones IP & SIP trunk?

    you have enabled the "run on all nodes" for a list of course also?
