We have an asterisk box at our main location, with many remote locations, connected via a VPN network. On each VPN link, we have a 128k 1:1 PVC (seperate virtual link dedicated for voice).
We use SIP/alaw, so we can only use 2 concurrent channels on each remote location.
I was playing around with groups to limit this, but then I have to validate every call in every location to see if they use the link, and then put them in the appropriate group, and check the nr. of channels before proceding with dial command.
Any of you have encountered a similar situation ? Is there a beter way (more easy to administer etc.) to do this ?
by the way: what would be the symptoms when having more channels than bandwith allows ?
Thanx in advantage,
