I'm troublshooting a RightFax issue and am trying to determine the cause of a failed transmission. The context is;
- RightFax is attempting to send an outbound fax via H323 trunk to the gateway.
- Outbound fails with the following q931 information;
Dec 9 16:43:49.755: ISDN Se0/0/0:23 Q931: RX <- CALL_PROC pd = 8 callref = 0x803E
Channel ID i = 0xA98397
Exclusive, Channel 23
Dec 9 16:43:50.011: ISDN Se0/0/0:23 Q931: RX <- ALERTING pd = 8 callref = 0x803E
Progress Ind i = 0x8288 - In-band info or appropriate now available
Dec 9 16:44:02.020: ISDN Se0/0/0:23 Q931: TX -> DISCONNECT pd = 8 callref = 0x003E
Cause i = 0x81AF - Resource unavailable, unspecified
Dec 9 16:44:02.052: ISDN Se0/0/0:23 Q931: RX <- RELEASE pd = 8 callref = 0x803E
Dec 9 16:44:02.072: ISDN Se0/0/0:23 Q931: TX -> RELEASE_COMP pd = 8 callref = 0x003E
On the disconnect error "Resource unavailable, unspecified", it appears that it is happening during the transmission phase (TX). Does this mean that the failure is happening on the RightFax side, since it is initiating the outbound connection?
