Adtran has been installed for years and two weeks ago, faxes through adtran fail.
Every once in awhile a few get through.
My customer only receives faxes.
the path is: 2 sip trunks > 908e > isdn > customer equipment > customer fax
I only have access to the 908e.
from the sip trunks going toward fax:
Sdp= m=audio 10158 RTP/AVP 0 8 18 101
908 toward sip trunks:
m=audio 10004 RTP/AVP 18 101
but I don't get the re-invite for t.38
It looks like to me that we are receiving a disconnect from the isdn.
Does anyone know what the stuff in green bold is?
Thanks in advance.
