Cisco 2921 CME SIP Trunk 503 Error

Greetings Everyone,

 

I am trying to implement SIP trunk thru our current data circuit with below call flow. I was able to get the SIP registration with SIP carrier and when I make a inbound call from my cell phone to one of the SIP carrier provided DIDs then I get fast busy. I was able to capture the packets on my CME and I see call coming thru with my number but I see 503 Service Unavailable Reason: Q.850;cause=0. I cant make outbounds calls either.

 

Call Flow: Polycome phones -----> Core Switch -----> Cisco 2921 (CME Router) ----> Cisco 4451 NAT/Zone Based Firewall Router -----Internet ------> SIP Provider.

 

Below are the partial logs.

Re: Cisco 2921 CME SIP Trunk 503 Error

I can see both To and From fields have a @sipcarrier.com URI. I understand you are masking the IP addresses with @sipcarrier.com so, was this log copied/masked correctly? The To field should not have the sip carrier IP address in the URI but your CME IP address.

Beginner

Re: Cisco 2921 CME SIP Trunk 503 Error

Yes, masked correctly but those debugs last 2 messages, some more debug messages below.

 

10.109.205.20 is my CME IP address.

Re: Cisco 2921 CME SIP Trunk 503 Error

I was able to get this working by removing the outbound proxy command from my incoming dial peer and now I see incoming calls but my outgoing is still an issue.

 

Below is the outgoing dial peer, any suggestions. I get same 503 service unavailable error

 

dial-peer voice 210 voip
preference 2
destination-pattern [2-9]..[2-9]......
media monitoring
session protocol sipv2
session target dns:SIP.com
incoming called-number 9T
voice-class codec 1

voice-class sip options-keepalive up-interval 12 down-interval 65 retry 3
voice-class sip pass-thru content sdp
voice-class sip bind control source-interface GigabitEthernet0/0/0
voice-class sip bind media source-interface GigabitEthernet0/0/0

What is the configuration of your GigabitEthernet0/0/0?

Re: Cisco 2921 CME SIP Trunk 503 Error

Looks fine. Can you run both debug ccapi inout and a debug ccsip messages and share the log of a test call? And can you do the same with an outbound call?
