Sangoma ISDN How to send CONNECT ACK to Net-side for outgoing call (User to Net)
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)? Thanks to all. With best regards, Shumaev DA, KBR Ltd.
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. On Mar 2, 2013, at 4:59 AM, Dmitriy Shumaev <pm_zefman_r@mail.ru> wrote:

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)].
