I know this topic has been discussed more than 100 times, but i'm not sure about this scenario:
CME with 4 FXO ports. One port is a dedicated line (Support) with hunt group configured to ring at 2 IP Phones. After working hours, the IP Phone users will use the CallFwdAll to direct the line to his moible number.
The problem is that after working hours, when someone call the support hotline, the call will be directed to the mobile line of the support (using one FXO port). If no one answers the mobile line, after around 10 ring, the mobile will stop ringing (the mobile operator timeouts) and the client will receive a re-order tone.
In this case, the FXO port used in the CallFwdAll will get stuck, and the router doesn't release it, until we perform the shut / no shut.
We have tried alot of cptones, and custome cptones, but with no success. Taking into consideration that other disconnection problems are solved.
Could this be solved? should we look more into custome cptones?
Now i have upgraded the scenario, now i have two sites.
Clients dial support hotline (FXO) --> (Router A) --> Connectio plar opx to extension 8028 --> dial-peer voice voip 8208 --> VOIP --> (Site B) --> UCCX --> After working hours --> Call Redirect to moible line --> (Router B) --> FXO --> Mobile.
The disconnection problem here is that when the call ends, the FXO at router A and FXO at router B are stuck.
Check that sometime you will received different diconnection tones depending on where the call goes, e.g tones from mobile network are different from fixed. In that case it become practically impossible to have it working.
You gave me an idea for another test. I tried to transfer to a landline, the disconnection worked fine! But only when transferring to a mobile line, the disconnection problem remain.
