I tried it here. For me it works - of course... However, I was using snom version 7.3.14 and there all SUBSCRIBE messages now show Expires: 0. Needed to change that to 3600, then it was much better.
I would just use one auto attendant and 24 service flags. One falg for each hour. Then use the night mode feature to distribute the call to each cell phone:
Service Flag Account: 7100 7101 7102 7103 ...
Night Service Number: 9787462777 9787462778 9787462779 9787462780 ...
You can even make exceptions for the weekend and for the holidays!
No, the blue line is the number of call legs. Usually one call equals two call legs. The red line is the number of calls, and in that graph the maximum was three calls.
Hmm. What if we just introduce a setting that says "maximum number of connected calls" in a agent group? In the above example, set it to "1" and then that poor guy who is on duty can work without phones ringing around him.
Do you get a admin email about the disconnect? That would be a clear sign that the PBX thinks the call dropped. Also, check if the AudioCodes has VAD turned on (turn it off if that should be on).
Nono. The PBX must find that out automatically, and it is possible. The routing table of the PBX make that possible.
I believe in this current case there must be something wrong with the setup. We are trying to get a login and find out what the problem is.
Hard to say why the provider sends forbidden back. Are you sure you paid your bills?
Interestingly, they seem to run pbxnsip as well. They even use the same version as you do!
May be a stupid question: Do you actually see the BYE message showing up on the PBX? Do you see it in the log file? Maybe the PBX is not aware the call disconnected yet.
The last time I saw a VAR dialling 911 and talking to the officer saying "Hi, we're just installing a new PBX and testing if it works. Have a nice day." No firetrucks showing up in front of the building.
"cell_dis" means "Display" and it can contain strings like "(978)746-2777". The cell phone number in "cell" is being used for making calls and it would typically contain "+19787462777" (if you use country code 1).
Try establishing an audio call first then switch the video on (while still talking). Essentially the PBX believes it is T.38. Fax and video are actually similar.
