[asterisk-users] Problem with phantom calls

[Giancarlo Rubio]

Hi everybody:

I'm having a problem with asterisk 1.4.22-3 on trixbox, This server
have 8 lines connected at SIP VOIP provider vono in Brasil, all calls
going to a same queue and are answered with 4 attendent on other
network and location connected via PAP2 over nat. When the network
down, in asterisk or pap in other locations, calls hang up but doesn't
close on asterisk (Phantom call).

All the docs and forum for solution are reading, various options are
setted on asterisk and the dial command, but no success. The last
place to contact and solve (if i'm mistaked on concept or config) are
here, otherwise is a bug on asterisk.

Options used on call that i will try to solve (but no solved)

* Dial whit (s and S) Dial(sS...)
* silencedetecthangup=25 (on all sip clientes and provider) [1]
* I have read the bug 207 on digium [2] but no success

I think are a config on queue that result on my problem

For example, look at the first link on channel SIP/3008-add0f320,
duration 20:26 (is infinitly) the pap client on 3008 are UNREACHABLE
and the call are UP
