Hello Everybody ,
we want relay fax from as5350xm to the sip server. So,I have configured fax(t38 protocol ) on as5350xm gateway and the Sip server ,
Now the signaling is Properly working , but we couldn't hear or receive fax tone in fax machine, I'm confused that whether gateway must relay a fax tone to fax machine or our sip server ?
the connection establishment is ,first the IVR is played then we click on start button on the fax machine and nothing could be hear and then the gateway send the invite fax(t38 SDP) to our sip server , also it receive 200 OK(t38 sdp) and response as ack .
I don't know why the data (fax) couldn't transfer .
Furthermore , the packet that we receive on our Sip Server , is the same as below , but we couldn't interpret it. all of the packet are 172 bytes and ,the following 3 packets are the first three packet that we receive in one call and also followed by many other same packet.
are these special t30 packet format that based on ITU ?

Hi. The IOS 12.4.9 is a dated IOS (probably 2007).
Can you try a new IOS like 12.4.24T8 or 15.1.4.M8?
Can you add the full wireshark trace?
From image I can't see the packet details.
During a call you can run the command "show call active voice compact" and post the output?
Regards.
