Hi, i'm fairly new to the world of voice so please bare with me on this one
I'm upgrading a customer from analog telephony to VOIP and the customer wants his faxes working.
Telephone works fine, CUPC works fine, CUBAC works as it should etc but the fax-machines can only receive faxes, not send them.
The setup is:
CUBE Version 15.1(3)T1
I'm using T.38 and SIP
When i put 2 fax machines on the new solution and test them they work. They can send and receive faxes but then the traffic is local and not sendt out over the IP-trunk. When i send a fax to a fax machine (from external) it works but when the same fax machine tries to send a fax externally it failes.
It places the call but when it tries to send the fax it gives up.
I've atteached the "debug voice ccapi inout" and "debug ccsip all" from CUBE for details.
This is the last issue i have to get this customer flying on Cisco equiptment (i hope).
Sorry for misleading you on that one. I know its on the trunk
And i believe i found the cause of my problem. The DN wasnt presented the way the the provider wanted it.
The misleading part was that it failed on media negotioation, not on the call. The log even tell the story of media negotiation being succesful but it also terminates on "cause=64" which is media failure.
I was able to place calls, receive call and receive faxes but not able to send any fax at all. That through me off thinking there was nothing wrong.
