That's how I have it setup.  The ITSP is Voxitas.  I'll try to do a capture and 
see.

Subject: Re: [sipx-users] T.38 Faxing on SipX 4.4 Setup

the fax did goes in unified messaging and only appears if an email address is 
entered. you need to create a fax "line" and DID there.

i.e. user 200, unified messaging FAX is 300 and DID is 19725551212

sipx does t.38, which means the itsp needs to send the call using t.38 or send 
it g.711 and upon hearing CED tone from sipx, send a re-invite for t.38. If the 
ITSP is using a SONUS switch you will likely not ever get a successful fax 
either it seems.

i would suggest a call trace or a sofia.log in debug if your itsp says they are 
sending in t.38 and you have completion issues. Calling from a cell SHOULD go 
silent after a few seconds, there is no CED confirmation from a cellphone.

who is the itsp?

Question about T.38 faxing on the new 4.4 SipX version.  We just did an update 
from 4.2 and voice is working correctly.  Our ITSP has T.38 support.  Is there 
anything
Specific we have to do to configure faxing besides assigning an extension/DID 
to a user profile?  Do we also have to create a user in SipX with this 
extension/DID alias?
I tried a test fax to the DID assigned to my user account and it does not 
complete.  Tried dialing the DID with a mobile phone to see if I get the fax 
tones, but it sounds
Like it is incomplete… get what sounds like the start of nego (a beep) then the 
call drops.
