I have the following setup:
PSTN (8 analog incoming lines) -> Panasonic PBX
I would like to place Asterisk as IVR behind legacy PBX.
How many FXO/FXS ports I’ll need to be able to handle all 8 lines?
IVR will basically prompt a caller with welcome message and ask him/her to dial an extension. Then asterisk will transfer this call to the proper ext. on the panasonic PBX.
I’m familiar with Asterisk and IVR configuration. This is my first integration of legacy pbx and asterisk.
Thanks in advance,
