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.
