[Freeswitch-users] Problem with freetdm+libpri (euroisdn): T316 timed out

[Ashish gautam]

Its a bug probably due to which only 2-3 channels get started. You will
have to make little changes in the source and recompile mod_freetdm and it
will be done. Just follow these steps:


   1. Go to FS source directory and change dir to this
   path libs/freetdm/src/ftmod/ftmod_libpri
   2. change #define T316_TIMEOUT_MS_DEFAULT to 10000
   3. #define T316_TIMEOUT_MS_MAX to 300000
   4. #define T316_ATTEMPT_LIMIT_DEFAULT to 30 (max. channels in PRI lines)

After this recompile mod_freetdm and restart freeswitch. You will see
channels restarting one by one. Also during this period in which the
channels are restart do not make calls as it will show
NORMAL_CIRCUIT_CONGESTION. It will take some time to restart the channels
and after that your PRI line will be up and running.
