PART-2
Presently market is growing with IP PABX and lots of existing PABX are digital or analog or hybrid system.
In this situation how can we interface IP PABX to other legacy PABX that have no E1 or ISDN PRI interface option or unavailability of necessary card/modules/licensing.
In that case we can use analog trunk port, Analog station port and SIP station port for PABX to PABX tie line interface.
CASE-1: IP PABX to Analog/Digital/Hybrid PABX System interface
CASE-2: Analog/Digital/Hybrid PABX to Analog/Digital/Hybrid PABX System interface
