Is it possible to link digital PBX and analog PBX?

Question

Telephony

There is an analog PBX operating at the enterprise, a newer digital PBX iPECS LIK-MFIM300 was purchased, with support for sip telephony, is it possible to connect the old PBX to the new one so as not to transfer "old" subscribers to the new PBX?

Answer 1

If no models.
Method 1: FXS gateway - connect CO ports of analog PBX to it.
Method 2: FXO gateway - connect to the free telephone ports of an analog PBX.
Both methods require you to know how to set up a PBX (difficult for an unprepared specialist).
If you do not configure anything, it will be difficult for users - make a table for them how to call where.
I did something like that - connected 2 analog exchanges - CO ports from one to the other telephone - it's okay - just think about dialing 99 to enter the city.

Answer 2

Solved this problem 2 times.
The 1st was purchased for an analog PBX sip card
. support for E1 was already present in the analog one.
The easiest option is to buy gateways.
