FAX Call Issue over SIP Line

[abdul rasheed]

I have an Imagicel FAX server. 3 Analog FAX lines and a few SIP FAX lines(SIP Trunk). I can send an receive FAX between my analog lines (through PSTC/For Testing). Also, I can send and receive between SIP FAX lines (Through ITSP/For testing purpose). But I can't send or receive between the SIP and Analog Lines. Some time shows protocol timed out. Other time it is Unknown. Looking for your great support.

What is the fax protocol in use ? What is the call flow over which your faxes are failing ?

Hello Nipun,

Thanks a lot for a quick response.

I am using T.38. The call flow is as below:

MS Outlook(Sender-SIP) -->Imagicle FAX-->Cisco CUBE-->ITSP--->PSTN-->Cisco CUBE-->Imagicle FAX-->MS Outlook (Reciever-Analog).

Attach your CUBE config. Also get a log for the following debugs for a failed fax from the CUBE -

debug ccsip message
debug ccsip error
debug voice ccapi inout
