I had an analog phone off the hook for quite a while, and it was showing up as the “Rsrvd” state while playing the congestion tone.

Hope it helps!

I currently have a problem that resembles your one, i have a 4 port E-1 card and i use the G1/ configuration, after a few phone calls Port 124 and subsequently it works downwards, goes down for the count and sits in Reserved state and wont come out of it. I have to restart Asterisk 3-4 times a day just to get back my channels or i run out of capacity.

I have a Sangoma card, we didn’t experience this with the Digium card, however that was on an entirely different system with a different build of Asterisk. I know this is an Asterisk issue and not a faulty card, but finding out what is causing this problem is beyond being a nightmare i tell you.

These are the Telnet Event messages i get:

Event: Newchannel
Privilege: call,all
Channel: Zap/113-1
State: Rsrvd
Uniqueid: 1171536671.46

Event: Newchannel
Privilege: call,all
Channel: Zap/120-1
State: Rsrvd
Uniqueid: 1171536752.56

Event: Newchannel
Privilege: call,all
Channel: Zap/115-1
State: Rsrvd
Uniqueid: 1171539668.503

Once i get that, boom thats it the channel is no longer usable, any attempt to send a call to that channel results in failure, this is the result i get when a call tries to go to that channel;

Response: Error
Message: Originate failed

I have been working on trying to resolve this problem now for over a month, no luck yet and i am running out of puff with this problem.

I hope you find a solution for this problem, cause i am damn interested to know, right now we are looking at the scripts too see if they can be causing the problems, but i am afraid i wont find the answer soon enough.
