[asterisk-users] Load Balance Trunks

[Abid Saleem]

Dear Steve Edward,
I appreciate your response and help. Here are the answers inline to your questions. Please help me in writing an AGI script or whatever required if you can as I am not a programmer.
Is your intent to 'load balance' between 100 trunks or will you fill up > one before moving on to the next? Can unused capacity be 'rolled over' to > the next day?Abid -> The intention is to load balance between 100 or even more trunks. Filling up one trunk may have another problem because we have another restriction on 5 simultaneous calls per trunk. Yes unused capacity can be rolled over to the next day. Anything is fine that does not break these two restrictions of 120 mins/day/trunk and 5 simultaneous calls/trunk. > What happens if you 'go over?' Will the call in flight be terminated? Will > the next origination fail? Will you get a nasty rate spike?Abid -> If we go over, the call will not be terminated nor the next origination will fail nor we will get nasty rate spike but they will send us warnings and then finally block our trunks.

Best
Regards,
