[asterisk-users] UDP miss a hangup on SIP

[Jerry Geis]

Is it possible to miss a UDP SIP packet to hangup a call?
Using 1.4.43 I had a call from on asterisk box (server) to a
low end client (chan_alsa) not hangup.

Could this be due to missed UDP SIP packet to hangup?

Is there anyway for a client asterisk (chan_alsa again) to
monitor the connection and if the channel is not there to
hangup?

Thanks,

Jerry
