finally found a solution for stuck channels. Im sharing this for anyone who may face this problem in future. It seems a bug as i can repeat this behaviour both ways as many times as i want. i will start an issue for this on digium bug site but first i have to test it on the latest version of asterisk.
<br><br>Asterisk loses binding with peers somehow if qualify=no is set in sip.conf. when asterisk loses binding it does not know that the peer is now UNREACHABLE becoz it does not monitor it all the time due to qualify=no. So when a call comes for that (UNREACHABLE) user asterisk tries to send sip packet for that user which the user does not recieve. Asterisk has no problem with that, it only throws call to voicemail or whatever is defined in dialplan. But after hangup channel get stuck.
<br><br>If we set qualify=yes, then asterisk keeps track of users whether they are REACHABLE or not. So if any user is UNREACHABLE it knows about that user and does not bother to send sip packets to that user anymore. This way channel is not even initialesed if sip invite is recieved for that channel (and goes directly to voicemail) and uninitailised channels cannot get stuck.

here is the sip debug for the channel. Before reading the sip debug i want ot tell you that user is using "Telco Systems AC-211 v4.50.27" adapter. sip sdebug shows that asterisk is trying to send the initial invite but there is no response from the user (after registration, user dies, no single response). So maybe there is some kind of network issue (NAT) or there is something wrong with the Telco Systems adapter. The stuck channels are still there:

<br><br>I call a user A, from user B. user B hears silence, untill it goes to voicemail. when user B hangsup. user B's call limit is reset to 0 but user A's call limit is not
reset.strange thing is user A's status on cli is shown as NOANSWER, while user B did not even hear ringing. when i use "sip show channels" command, it shows me a channel for user A like below:<br><br><span style="color: rgb(0, 153, 0);">
crunch 30d926c1055 00102/00000 unkn No Init: INVITE<br clear="all"></span><br>It stays in INVITE state unless i restart my asterisk server. when i restart the channel is clear (ofcorse)<br><br>So my guess is, its a zombiee channel which asterisk forgot to hangup. WHY? i dont know, maybe there is a problem in sip signalling due to which asterisk didnt recieve the bye signal in the first place or maybe its asterisk fault totally.
<br><br>So because it is not hungup by asterisk thats why its call limit is not reset to zero. I dont have sip debug for this problem yet, i'll post it later when i have it. meanwhile if somebody has experienced a similar problem and has successfully fixed it, then plz share my burden and help me.
