There are a lot of fields/parameters to configure sangoma isdn module. One of them - "send-connect-ack" [/FSW/libs/freetdm/src/ftmod/ftmod_sangoma_isdn/ftmod_sangoma_isdn_cfg.c :: ftmod_isdn_parse_cfg(2)]. Please, add this parameter in [http://wiki.freeswitch.org/wiki/FreeTDM] with link to [Q.931 :: Figure A.2/Q.931 – Overview protocol control (user side) (sheet 2 of 7)].

Sangoma has the code set to not send the connect_ack even when required by spec without some param set. Please contact sangoma support for details on what needs to be set.

Hi
I have a problem in connection of Sangoma A101 board and LG LDK-100 PBX. Incoming calls from PBX are processed successfully. But outgoing calls to PBX fail because of T313 Timer = 4 seconds between CONNECT and CONNECT ACK. Simplified diagram of the Q.931 signaling is next: User (Sangoma, cpe) <-> Network (PBX LG) -> SETUP <- PROCEED <- ALERT <- CONNECT // 4 seconds <- DISCONNECT (Recovery on timer expired) -> RELEASE <- RELEASE COMPLETE . Full log and sangoma configuration files are attached.
As stated in [ITU-T Q.931 05/98 :: Figure A.2/Q.931 – Overview protocol control (user side) (sheet 2 of 7) :: page 186] - CONNECT ACK *could* be sent.
So, how can I configure FSW to send CONNECT ACK for outgoing calls (if it is possible)?
