Configuration ExpresswayC/e 8.5 for B2B calls fails to external domains

Hello

I am trying to config Highway C/E for B2B scenario.

The end user has no DNS Public so all the resolution is by its public IP address. In addition ExpresswayE has an IP address in the DMZ (single NIC option)

I have the following problem:

Call (h323 or URI) of the remote third listening outgoing calling for and after answering no video and voice.

For incoming calls, the remote side to see the appeal abandoned, no dial tone and the premises of the party never listen to ringtone. In ExpresswayC I do not see

the call attempt, I can see the call to ExpresswayE attempt.

I followed a guide of configuration, but actually I'm not sure of the rule processing and research I have to config in highway C/E

When there is no Public DNS.

You have inspection of SIP on your firewall? If so, try turning it off.

  • RMS Expressway Cisco licenses for B2B calls

    Hi Experts,

    We have Cisco Expressway Setup for B2B calls. We have 6 licenses RMS across Highway C & E, making 3 on EXP E and 3 on EXP C.

    Now, I'm able to do 3 Conference of the party including the host. Myself and 2 other B2B calls for a video conference. Where that we watched for 3 with the exception of the host Party Conference.

    We were under the impression that if we buy 3 licenses RMS, we have 4 video party conference. It's 3 outside calls excluding the host.

    Can someone explain how the RMS license.

    Our IPT put in place:

    CUCM 10.5

    SX20 - recorded at CUCM

    Motorway C - containing 3 licenses RMS

    Highway E - containing 3 licenses RMS

    Concerning

    Benyoucef

    Hi, Renaud,.

    Licenses RMS are concurrent, so in your case both licenses RMS (one in each Expressway) per call are necessary. You can check the following positions related to similar queries

  • Highway X8.2.2, Changing default SIP Port for B2B calls is not possible

    Much of community support.

    I 10.5.1 (SU1) of CUCM and X8.2.2 Expressway.

    I have configured without VPN Jabber and B2B based on the Document calls "CVD-CollabEdgeUsingBE6000 - Apr14.pdf.

    everything worked fine for months, but after the upgrade of the X8.2.2 Express way B2B calls are no more work.

    After troubleshooting, I found the following:

    the DSF Guide tells me to change the default Port to 5061 to 5560 B2B calls because 5061 is also used for the integration of Jabber.

    When I look at my record of wirekshark I see cucm tries to connect to the port 5560 expressway, but after sending a SYN packet, cucm receives a RST packet.

    When I change back to the port of 5560 to 5061, everything works well again for B2B, but of course encrypted calls Jabber connection is not possible more.

    for me, it looks like a bug, but I found nothing on the 'Bug search' tool.

    I also tried to disable all Protection rules and I also have a firewall rule for Port 5560. I also tried to change the TCP Port to something different, 3999 for example. All this without success.

    Just a little look in the guide.

    Two caveats. First thing the guide explains unencrypted SIP - TCP connections, if you want to be aware that both sides use TCP or TLS. If you are using TLS certificates must be good as well.

    5560 isn't a port on the highway, this is the port for the trunk on CUCM.

    What do you see CUCM sending to Highway: 5560 Setup is not ok.

    The port of the highway will not be changed.

    If you look at page 30, he 5560 port is used for the "incoming Port *" and the bottom of page 31

    You can see that it uses the Expressway IP with port 5060.

    On the highway, you configure the area to port 5560 (page 34)

    And of course the firewall should also be ok.

  • SIP URI B2B calls via CUCM and Highway

    Hi all

    Cannot find out how to configure the SIP URI from SX codecs, recorded calls on CUCM.

    I CUCM and IM & P 10.5.1 a pair of X8.5.2 expressway with two areas of course - for B2B calls, and the external jabber.

    I want to make calls of SX-codecs outside via SIP, by using the URI field, for example, [email protected] / * / or [email protected] / * /. How can I configure that?

    I already have the routing model, which is the SIP Trunk for Exp - C, for H323 calls by ip address. Is it possible to make a routing model to call the SIP URI?

    You can see my deployment in this image.

  • How to set up a '0' prior to call for outside calls (CCM 6.2.1)

    Community salvation.

    I think that this issue could be very easy to be decided by the experts of the calls voice cisco. What are the steps required to configure all the internal components of the phones that they must dial '0' to get an outside/international appeal of prior work? Is it a matter of templates for itinerary?

    Thanks in advance.

    Kind regards.

    Hello

    Yes, it is a RP "template routing." I hope to share with us your topology what your CUCM & gateway type (MGCP & H323). In any case regarding steps e, please find the below: -.

    1-configuration of your gateway that will be responsible for tree calls.on incoming and outgoing CUCM gateway device - select type.

    RG 2-group to configure or channel that will include your gateway recorded. CUCM call routing-road/hunting-lines group and assign your gateway listed

    3 - RL set which includes your RG that configured in step 2. Routing-road/hunting-other calls list, then assign the RG.

    3-model RP to configure or channel. for example

    0.161xxxxxxx for mobile

    0.00!                 for international

    At the partiton award

    B - RL that configured in step 3

    C - on the bottom, discard numbers "predot."

    Test; user dials a number that fits the RPS following 0.161xxxxxxx & 0.00!  the calls will go.

  • Voice mailbox for a call center?

    I am having some problems where for my call center messages go to the wrong mailbox. I don't know if we have this set up correctly. Any help would be appreciated.

    I have a Point of road SIC x 2288 (release of matches by the IPCC)

    I have two boxes of 2288 and 2287 unity voice mail.

    Now when someone calls technical support, they get the CSQ technical support or AutoAttendant CSQ (both are by the IPCC). When the appellant needs to leave a message, the call flow was designed to go to 2287, 2288 is a pointer of the unit until the Point of road of CTI. Can I have a voice mailbox configured to 2288 and remove the 2287 script? (A parameter, it is so easy to change). I'm not sure if change that will place the loop... call voicemail point to CTI road... that sends to the IPCC... to leave a voice message, they are transferred to 2288... who sends point routing CTI...

    How did he know to take a message, instead of to the front to CallManager?

    Is there an easier way or to create a mailbox for a call center?

    Normally, the voicemail box must be different from the CTI RP DN.

    So I think your configuration could be correct.

    If your CTI RP pointing to CRS is 2288, in the sript that you tap voicemail DN, if this would be the same, then you will need to make sure that the CTI port doesn't have access to CTI 2288 Point Road, to the parition assigned to CTI route point poinitng to VM. I would you recommend leaving the voicemail as 2287 box so that way you don't have to worry about the possible loop.

    What was your reason to change the voicemail box?

  • Call the menu Handler for a transfer out to external number

    I'm completely hide on that's why I can't understand this configuration... It's pretty simple:

    The appellant takes the phone and he made a call to the Unit Manager... The message says to the press '1' to be transferred to the technical support.

    I can do this with extension 4-digit fine to a transfer of Subscriber.

    But my '1' in this example must be the transfer of a number of external... How is this work?

    Thank you!

    You map either the 1 button for "attempt to transfer for" a call handler configuration to dial the external number (i.e. "9,1234567" in the chain of transfer) - or you can have 1 go to the conversation of "transfer system" which allows users to "free dial" the transfer number themselves (if he spends gathering with the restriction for this table). This assumes you're on a newer version 4.x of the unit.

    the former resembles what you want...

  • Cisco Jabber Im b2b calls

    Hello world!

    I m deployment the following scenario:

    CUCM--> exp - c--> exp - e

    I registered sx10 and cisco jabbers on Cucm and I've implemented mra and b2b on the solution of the highway. Of sx10 I can dial in the external domain, everythings and the external ip address work very well.

    Also, I downloaded jabber - config.xml for uri component of jabbers users but I have a problem: when I compose b2b calls from a jabber user, the call comes in the highway-c, but this uses the time zone of the mra to the highway e, then "Service unavailable" error. I have already added the b2b area and works well endpoint sx10, but not jabbers users.

    Can someone help me?

    Kind regards!

    Something weird going on here. Looks like Jabber's still doing this call as a call MRA.

    Try adding a SIP (area boss) route in CUCM for externaldomain.es and refer her to your B2B SIP Trunk 5560 to Expressway. Then restart Jabber and try the call again. If it does not please post again the history of the research.

  • I use my iPhone 6 very often to my office for phone calls.  This will help overall battery life to stay connected as I have all these phone calls?

    I use my iPhone 6 very often to my office for phone calls.  This is my work phone.

    This will help life battery together if I keep the phone plugged in my phone calls?

    Thank you

    SUSE, you can use it while connected and in this way when you unplug to get somewhere, you know you will have a fully updated beautiful upgraded battery.

    Just don't leave it plugged constantly all the time — weeks or months.  A battery lithium needs periodically some running through it.  But certainly leave it plugged during the day of the company while using it, or even just for long calls will do no harm.

    Battery life is determined by the cycles, so if this reduces the rate of your phone through equivalent full charge and discharge cycles it can not hurt self-help (depending on how you use it, it cannot help battery life much either, but it probably won't hurt it).
