Hello I have an ericsson md110 with asterisk Some of my clients are with ericsson and others are sip connected. I needed a call queue application and i created it on asterisk. I had to use static clients which are running on ericsson as follows; Members: DAHDI/g1/1472 (Unknown) has taken 27 calls (last was 4078 secs ago) DAHDI/g1/1241 (Unknown) has taken 13 calls (last was 4256 secs ago) DAHDI/g1/2964 (Unknown) has taken 1 calls (last was 94666 secs ago) DAHDI/g1/3560 (Not in use) has taken 22 calls (last was 2272 secs ago) DAHDI/g1/3561 (Not in use) has taken 23 calls (last was 1210 secs ago) DAHDI/g1/3562 (In use) has taken 13 calls (last was 73853 secs ago) DAHDI/g1/3563 (Not in use) has taken 31 calls (last was 19 secs ago) Problem is, as you can see some of clients seems as Unknown some are as not in use. And one of them is seem in use even it is not. All that clients are connected via PRI. And i can not know if they are actually in use or not. This values seem random to me. I am running 1.6.2.0-1 asterisk with DAHDI Version: 2.2.1 Is it a known issue? Is it a kinda bug and is there a way to recheck the status of the client in anyway.. Because as i got ringinuse=no rule, this client can not accept any calls.
