ccb->cc_disc_cause (38); ccb->sip_disc_cause(503) error via SIP trunk

[Rajkumar Yadav]

Hi,

I have issue with sending the call to the Neogate GSM VOIP gateway via SIP Trunk.

I'm getting error as "Cannot get remote address for connector socket" and "ccb->cc_disc_cause (38); ccb->sip_disc_cause(503)" 

I understand its 503 error, no response from the Neogate, but able to ping the CUCM IP address.

below is the log for failed call.

Hi,

To clarify, is it the call flow?

Phone -> CUCM -> SIP Trunk -> NeoGate GSM VoIP Gateway

Thanks

Vivek

[Aditya Gupta]

Hi Vivek

Is there any firewall between CUCM and the GSM voip Gateway ?

Can you verify port number 5060 is opened for communication ?

Regards

Aditya Gupta

[Rajkumar Yadav]

Hi,

The call flow is right as you mentioned, as what i discovered the VOIP GSM gateway does not accept the TCP stream and that's the reason it rejects, i changed the outgoing message as UDP in sip profile for sip trunk.

Also the disable the firewall functionality, port/ip address balck list.

Now i'm getting the error as  "ccsip_api_call_disconnected: ccb->cc_disc_cause (1); ccb->sip_disc_cause(404)"

Regards,

Raaj.

Hi Raj,

404 Not found is generally sent by third party SIP gateway when there is no further route/destination to route the call. You can cross verify the dial plan is configured correctly in your gateway to route the call to desired destination.

One more point I would like you to take care about avoiding delay offer. Many third party SIP gateways either doesn't accept initial INVITE w/o offer or misbehave. By default, CUCM sends INVITE w/o SDP offer. You can control and change this behavior by enabling early offer under SIP Profile.

Thanks

Vivek

Hi Aditya / Vivek,

Issue is resolved and attached is the reference snapshot to get more understanding.

I was missing the incoming called number in Neogate GSM voip Gateway and only thing which was not allowing call.

Thank you very much for helping here.

Regards,

Raaj.

[Aditya Gupta]

Hi Rajkumar

Is it possible to get sip messages from your GSM voip gateway ?

Please paste the output here

Regards

Aditya Gupta

[Rajkumar Yadav]

Hi Aditya,

I will try to get the sip logs from there and post here.

(it will may little time as i have to visit at client site for this).

Regards,

Raaj

Hi Aditya,

Just fyi, post was by Rajkumar Yadav :)

Thanks

[Aditya Gupta]

Yep, noticed that later

My Fault :)
