I am new to Asterisk and hope to start testing 1st Q 2008. Is it possible to setup alternate call routing for inter-office calls? If we setup voip for inter-office calls across our WAN, can we limit the number of channels used for voip and make a rule that the system will use provider analog lines?
For example, if we can only tolerate 5 voip calls, can Asterisk follow a rule automatically so that the 6th inter-office call goes out an analog line from a phone carrier?
Thanks
