I am using conference call service of Freeswitch over ESL with 21- 22 members over GSM for around 1 hour. One problem that I am facing is frequent call drops of the connected callers.

My program has a logic of redialing a caller in case of disconnection, if the caller is not reachable due to some reason the redial happens three times. I am maintaining sufficient balance to keep 22 channels in parallel and also for the duration of calls.

One thing that I am observing which I am not sure to be the cause is when I increased the redial trial to five times, the frequency of call drops increased.

Is the dialing attempt count should be taken care for the balance maintenance or there is some other cause ?

The Freeswitch logs are of type - CALL REJECTED, USER BUSY
