Hi All

The IT department in one branch office is planning to connect one of the PSTN links from the Lecagy PBX to the VoIP Router, I would like to know people if my VoIP router is hardware prepared for that change. (I already know's the configuration).


Here is some information:

Hi


You have lots of hardware.


You should find out what type (physically, e.g. analogue, e1, rj48/45 or bnc) and signalling method (QSIG, DPNSS? PRI?) the PBX will use...


For further advice it's probably best to describe your scenario more fully...

You've got plenty of hardware to at least connect 4-8 E1s

Thanks, it was, It is just I think I needed more DSP's beause I only got 27 TDM ports configureng my E1 cause of the lack of DSP's


Thank you.
