Call Disconnect 404 on New AT&T SIP Trunk for Inbound Calls

Michael Mertens
Level 1
Level 1

Hello, I'm trying to provision a 2nd trunk with AT&T on a Cisco CUBE. Outbound calls work on trunk#2 but inbound calls on trunk#2 to the test number gets disconnect 404. The Test Number (TN) is 845-592-6506, which gets translated to 26506 and sent to CUCM, which has the DN on a phone. 

I do not have access to CUCM, but it almost appears that CUCM cannot route the call to the DN. Please see the below attached config, a screenshot of the FW sniffer trace (our outside IP is 32,253,59,194 and we translate that to 10.45.2.97 on the inside), debugs of "ccsip calls", voice dialpeer inout, ccapi inout, voice translation....

Any input would be appreciated!!!

Thanks!

Hi,

I'd configure an incoming dial-peer to capture the incoming call from the provider. With SIP, it's recommended to match on the VIA header, which will contain the IP address of your providers signaling endpoint.

Something like this:

voice-class uri 1 sip
 host ipv4: <AT&T Signaling IP>

dial-peer voice 1 voip
 translation-profile incoming onsemi-pstn-in
 #description INCOMING FROM AT&T###
 session protocol sipv2
 incoming uri via 1
 voice-class codec 1
 dtmf-relay rtp-nte
 no vad

As the translation will occur here, you shouldn't need any further translation applied to your dial-peers facing CUCM.

I'd also consider reconfiguring dial-peer 6000000 to look something like this:

dial-peer voice 6000000 voip
destination-pattern 26506
session protocol sipv2
session target ipv4:10.46.52.65
voice-class codec 1
dtmf-relay rtp-nte
ip qos dscp cs3 signaling
no vad

There are other improvements which can be made to that config, but just focus on getting calls into that number first.

Also for the outbound calls coming from CUCM to CUBE, it is also recommended to have an incoming dial-peer to capture these calls coming from CUCM and then your standard outgoing dial-peer from CUBE to SIP carrier / ITSP, like the one you already have configured.
The incoming dial-peer from CUCM would be written similar to my example above, but with your CUCM IP addresses and applied to a different dial-peer.

To collect sip logs, you should use "debug ccsip messages" which capture all incoming/outgoing messages. 

Anyways, your logs show that the call correctly matches dial peer 6000000 and the CUBE sends the call to the your CUCM after translating the called number to 26506. The CUCM disconnects the call with the Cause Value=1 which means Unallocated (unassigned) number. 

Please verify the following.
In CUCM, make sure the Calling Search Space used by the SIP Trunk (under Inbound Calls) can access the partition of 26506.   
Make sure extension 26506 is properly assigned to a phone. 

As @TechLvr mentioned, your debug says cause code 1 for disconnect. Which mean its an unallocated/Unassigned Number. This must be due to the New trunk created on CUCM doesn't contain inbound CSS which can reach the extensions 26506.

If you don't have access, reach out to the team who maintains CUCM and ask them to assign proper CSS on inbound direction. And make sure extensions 26506 is an assigned DN.

Thank you both for your input and fortifying my thoughts- sometimes I think I've lost everything I've ever learned in this field....

The site also had an ISR with a fxs VIC card. My dial-peer 6000000, I sent it over to the ISR, and created an POTS dialpeer, destination 26506, to point to that fxs port, and it rings (no answer), without the SIP disconnect 404. So as you both say, that confirms it is a CSS or DN-PT issue on CUCM or something else. 

Not to press my luck with you two, but during my troubleshooting, I noticed at the end of the "debug CCSIP messages" a "Warning: "No matching outgoing dial-peer"" whenever I called the number. However, my debug voice dialpeer inout showed I was matching...I've attached both debugs. Any thoughts on that?

THANKS AGAIN!!

Mike

About the warning: This is just how CUBE sends the "404 Not found" message back, even if the dial-peer was correctly matched in the first place. Probably default behavior, if the CUBE receives a 404 (e.g. from CUCM).

@Michael Mertens 
I still believe, on the CUCM side, the Inbound CSS of the SIP trunk cannot reach the partition of extension 26506.
Or it is also possible that extension 26506 has not been created/assigned to a phone. 

As you can see in the SIP ladder diagram below, the gateway sends the call to the CUCM successfully, but the CUCM responds back with a 404 Not Found message (Reason: Q.850;cause=1). From the perspective of the CUBE, cause=1 means "no matching outgoing dial-peer" (even if the CUBE received the 404 with cause=1 from the CUCM). The CUBE then includes its self-generated warning in the 404 message out to the ITSP.
