Hi all,
I've got a customer who's reporting ghost calls. Essentially, the phone
rings, they pick up, and there's no body there.
It is NOT one-way audio, and it doesn't happen all the time.
We use voipmonitor to watch calls, and this is what we saw for the call in
question:
| calldate
About a call not being hang up for asterisk while the client hang up,
please remember SIP is based on UDP and UDP packets get easily lost... they
are retransmitted but sometime they are lost as the previous...
For the ghost calls, are the SIP port of the phones reachable from the
Internet...
