Hi,
Didn't get any opinions on the log file I mailed onto the list over the weekend so I am continuing to try and track the cause for the dropped calls..
I have a feeling that its to do with IAX being way too sensitive when it comes to packet loss.. Since it is going across the internet it needs to be more tolerant when it comes to errors and packet loss..
Are there any settings (in the conf file or the source) that I can change to make it more able to keep the call connected without dropping it when there are errors even if the sound breaks up for a couple of seconds??
There's nothing in chan_iax2 that should cause a call to be dropped if there's packet loss for just a couple of seconds.
I think a call is not dropped until retransmission of "reliable" frames fails 4 times, if this happens, you should see something like this in your log:
"Max retries exceeded to host %s on %s (type = %d, subclass = %d, ts=%d, seqno=%d)\n",
Each retry is sent 10 times later than the first retry (up to 10 seconds). The first retry is sent at twice the round-trip time between the two endpoints.
