[cisco-voip] Fax issues

[Wes Sisk]

Jan 13 18:08:29: ISDN Se0/0/1:15 Q931: TX -> ALERTING pd = 8 callref  
= 0x83F7

Progress Ind i = 0x8088 - In-band info or appropriate now available

Jan 13 18:09:29: ISDN Se0/0/1:15 Q931: RX <- DISCONNECT pd = 8  
callref = 0x03F7

the disconnect is inbound to this router 60 seconds after the call  
goes into alerting state.
Alerting message means the destination is ringing.   This call was  
routed to some destination device and rang for 60 seconds without  
answer.


is the fax machine configured to auto answer?  does the analog line  
appear to receive ring voltage when you dial this external number?

Hello,

I have an ATA with a FAX. The CCM cluster has a MGCP gateway which is  
connected with a E1 QSIG to a PBX MD110.

If I send a fax from a fax located in the PBX side it works, but if I  
try to send a fax from an external location, this fax enters through  
the PBX and the PBX redirects it to the QSIG trunk.

When it doesn't work I have this error in the debug isdn q931:
