[Asterisk-Dev] PHP vs C

[Matthew Boehm]

Thanks for the info. We need our own LCR app because we will soon reach a
point where we will have multiple carriers with different rates for inter vs
intra, and intl vs intl-cell.
Do you use the php apps as AGI? I mean, is the php script called from within
* as an AGI?

Thanks,
Matthew
