Sip Trunk Faxing

I am om CCM 7.1.3 and have a connection to right fax server over SIP.I also have a connection to ATT SIP Trunk.

Faxing works fine in and out if I am routing out local PRI.If I change routing to ATT SIP trunk the call connects

the drops after 5 seconds in or out.

Sip Trunk Faxing

Hi, Ronnie

1.  If you got 2 sip trunk directly connecting to right fax server and ATT sip trunk in CUCM, you need to collect CUCM SDI, SDL trace for the failed call for analysis

2. it is better to open a TAC service request since this is a bit complicated issue.
