I would look at Standards Based T.38. EG MGCP on the VG224 , no SCCP. From: cisco-voip [mailto:[email protected]] On Behalf Of Dana Tong Sent: Wednesday, March 05, 2014 7:38 PM To: [email protected] ([email protected]) Subject: [cisco-voip] FAX and ITSP SIP Trunks and CUBE
Good morning all, So I have a pair of CUBE with SIP trunks to an ITSP. They are hard set to use pass-through G711alaw (Aus) and also explicitly set on each dial-peer with “fax rate disabled” as well. I seem to be able to send some FAXes ok back to my office along with some other machines at another company. I cannot however send to Telstra Test FAX and cannot RECEIVE FAX. The FAX is connect to a SCCP controlled VG224. Does anyone have any troubleshooting tips? I have the “debug ccsip messages” on the CUBE along with “debug voip ccapi” and “debug voice rtp session named-event”. Cheers Dana itevomcid
