I have a test t.38 trunk that is supposed to do the following: I have this set to T.38.
NONE - (default) Upon detecting a fax tone, no re-INVITE will be sent. TRANSPARENT - Upon detecting a fax tone, if the codec is not already G.711 ulaw, a re-INVITE will be attempted to switch to G.711 ulaw T.38 - Upon detecting a fax tone, our network will send a re-INVITE to attempt to switch to T.38. If the re-INVITE fails, a re-INVITE will be sent to attempt to switch to G.711 ulaw if the codec is not already G.711 ulaw. I do not see a re-invite being sent from sipx. I have only seen four packets during a tranasction. Invite with sdp, not offering t.38 from itsp. Trying. Cancel. OK. Since the call is being sent to a fax DID, I would have thought from earlier configurations that FS was sending a reinvite. I recall that discussion when testing earlier while working with devs on it. Has this changed? -- ====================== Tony Graziano, Manager Telephone: 434.984.8430 sip: [email protected] Fax: 434.326.5325 Email: [email protected] LAN/Telephony/Security and Control Systems Helpdesk: Telephone: 434.984.8426 sip: [email protected] Helpdesk Contract Customers: http://support.myitdepartment.net <http://support.myitdepartment.net>Blog: http://blog.myitdepartment.net Linked-In Profile: http://www.linkedin.com/pub/tony-graziano/14/4a6/7a4
