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.

HTH,

  • SPAN and SIP Trunk recording in parallel

    I'm looking to get away using a dictaphone SPAN and use SIP automatic trunk of the record (by using a recorder DMS Verint pool UDP) calls.

    My question is, if I apply SIP trunk recording simultaneously with recording SPAN, this mind? I need to make a CEP of the solution, but cannot stop the current recording.

    Thanks for any help you can give me!

    With the traditional port SPAN record in the Callmanager ignores the phone is registered, so when you activate the current record there will be no impact.

    However you can finish by double flow at the end of voice recording, so not sure what verint would do that.

  • How a dial-peer SIP Trunk using a Registrar?

    Hi all

    I'll put up a GUY using two records.  With the generous help of people on this forum, I got records in doubles to work.  But now I need to know how to configure the dial-peer to use registration information.  For example, I have this set up:

    SIP - ua

    Password 08114342101A0A1A43 7 authentication username 5555555555

    ...

    IPv4:11.11.11.11:6034 at the office 1 expires 3600

    Registrar 2 ipv4:22.22.22.22:6035 expires 3600

    How to configure a dial-peer to send traffic to one of the recordings?  I tried this, and it does not work:

    Dial-peer voice voip 105

    Description * outgoing SIP Trunk call *.

    translation-profile outgoing PSTN_Outgoing

    destination-model 91%...

    session protocol sipv2

    Registrar of target session? WHAT SHOULD I USE HERE?

  • 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.

  • Caller ID of VCS Jabber Video on SIP Trunk on the phone

    Hello, Netpros.

    I am trying to find a way to show a caller E.164 ID when a call to a video client Jabber a UCM or a PSTN phone.

    VCSC/E 7.1; 13.2 TMS, configured TMSPE.

    We have a VCSC > SIP Trunk > UCM (8,6) > H.323 GW w / PRI voice configured for the composition of and the PSTN destination.  We do this, so the Jabber client video can be used as a softphone, and so we can have transparent FindMe to voice and SNR to the video in either sense.  In TMS, we have a model of implementation configured with an address of the video, ILA and unit address.  He pulls ad office phone number for video of Jabber users.

    From what I read here:

    http://www.cisco.com/en/US/docs/telepresence/infrastructure/vcs/config_guide/Cisco_VCS_FindMe_Express_Deployment_Guide_X7-1.pdf, we should be able to see the caller ID when you call send out an ISDN GW.

    «This section describes how to use FindMe with calls are routed through an ISDN gateway (for example, when you call a mobile phone, or any other destination accessible ISDN).» If VCS has Caller ID (Applications > FindMe > Configuration) defined to use the ID FindMe, the identification of the appellant presented will be the user E.164 phone number. »

    UCM SIP config is vanilla, by

    ttp: / /www.tandberg.com/collateral/documentation/Deployment_Guides/Cisco_VCS_Ci...

    However, when a video call Jabber is directed to a University Complutense of MADRID registered phone, we get "unknown caller".  When to call us directly to the PSTN, we see that the BTN from the PRI.

    What is strange, is that if we call another client of Jabber of VCS (with all the same problems), directly into a phone UCM via Internet on URI (for example [email protected] / * /) through the VCSE, we see the caller ID name.

    Thank you, all!

    Joshua

    Hi Joshua,.

    At present the VCS will only send caller E.164 id to a GW of H.323 ISDN, which is registered for VCS.

    There a feature request in the order book to define if E.164 Caller ID or name/Video address on a per-zone basis. This will also be sove the question when the call is to go on a SIP connection, as in this case, a remote ISDN GW.

    Thank you

  • 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?

  • 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.

  • 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.

  • 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

  • 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?

  • 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.

  • ISE design question

    I have a few design questions about ISE v.1.0.4.573

    1. The ISE 3395 gigabit ports are supported on the aggregation of links?  How can I use all 4 ports uplink?
    2. When you perform an installation of 2 x 3395 HA, is there a connection of heart rate between the two ISE or they will use the same link to the network of pulsing and synchronization?
    3. I'm designing ISE with WLC. My setup WLC (5508) looks like 5 floors with different VLAN but same SSID. How can I do ISE authenticate in this scenario because WGB AP is not supported in ISE v.1.0. Is there a work around for this type of WiFi to the ISE configuration?
    4. Continuous configuration above, roaming from one floor to another floor after changing of Vlan, the user will be re - authenticate or use the same session?

    Thanks for the help.

    Kind regards

    Zohaib

    1. the current version does not support the aggregation of links...

    2. they use the same link to the network of pulsing and synchronization.

    3. my suggestion is to assign your SSID, a group of interfaces, containing all interfaces belonging to your VLAN, on your WLC and set AAA replacement. And then, at ISE, create authorization profiles include the appropriate VLAN. Use the Called-Station-ID RADIUS attribute with your MAC address of the AP as a condition.

    4. they use the same session.
