[asterisk-users] Strange incoming call issue.

[Leandro Dardini]

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... maybe it is just someone trying to place some free calls
