ccme -sip trunk to cucm calls not working correctly

Can someone help with an issue that I have?

I have created a sip trunk between a router running cme and the communicator manager.

I can make calls from the cucm to ccme but not vice versa. I get fast busy.

I have used the cucm configuration from this url , although I did not check the mtp box.

http://theucguy.wordpress.com/2009/02/20/how-to-configure-a-sip-trunk-between-cisco-call-manager-5x-or-6x-or-7x-and-ocs-2007-r1-or-r2/

The cucm registered phones has a directory number of  2724 and ip 192.168.15.244. The communicator manager is 192.168.15.1 with a route pattern 5xxx

the cme has phones with 5xxx  ip addresses of the  cme router are 10.200.40.2 and 10.250.250.3. Running 15.1T

The cme configuration is below, dial-peer 272:

CME_LAB#sh run | beg dial
dial-peer voice 9 pots
translation-profile incoming AA_CLI
translation-profile outgoing AA_CLI
destination-pattern 9...........
direct-inward-dial

I have used the command csim start 2724 and this is the result:


CME_LAB#csim start 2724
csim: called number = 2724, loop count = 1 ping count = 0

csim err csimDisconnected recvd DISC cid(62)
csim: loop = 1, failed = 1
csim: call attempted = 1, setup failed = 1, tone failed = 0

Also here is the output from debug ccsip all, the first being a call from a phone on call manager to a phone on cme (works) and vice versa (doesn't work)

Looks like a codec mismatch:

Media Stream             : 1
Negotiated Codec         : No Codec

Several issues here.

1.  You need dial peers supporting BOTH directions of the call (to the caller and to the called party).  With your setup, you are using the default dial-peer (which is a bad thing to do since you can't control it) to handle at least half of this.  You would be able to see this if you debug the dial peer rather than

2.  You have the codec on your dial peer set to G711Alaw.....If you're in the US, the correct codec is normally G711Ulaw.

3.  CCM cannot negotiate codec.  CME can.  You MUST have your dial peer exactly match the codec configured on the trunk on the CCM.ccsip

What would be the correct configuration for the incoming dial-peer?

I am in the uk and using alaw for the sip trunk.

Thanks

Hello Feisalb,

Would you mind trying this:

!
dial-peer voice 272 voip
description CCME_2_CUCM
destination-pattern 2724
session protocol sipv2
session target ipv4:192.168.15.1
dtmf-relay rtp-nte
codec g711ulaw
no vad
!

From the guide you followed to this:

1. Uncheck the MTP required.
2. DTMF signal method* OOB and RFC 2833

And if that does not work, please attach a debug ccsip messages, and attach a screenshot of the route pattern on cucm

Best regards,

Luis Sandi

Ok, I am the div.

Got it working by changing the destination ip address on the sip cucm to point to the serial interface 10.250.250.3 instead of 10.200.40.2 fastethernet sub interface.

Experimented a bit more and found the commands to bind sip to a particular interface.

voice service voip

sip

bind control source

bind media source

It is now working with the original dest ip 10.200.40.2

I guess it must be that same as using a source interface in h323.

The rest of the config is as the original, I didn't change the dtfm-relay to rtp-nte.

Next up is to see if cue voicemail works from phones on the cucm (loving all these acronyms).

I guess I will need a transcoder somewhere on the network to trancode g711alaw (5xxx phones) to g711 ulaw (cue) and vice versa.

Thanks
