[asterisk-users] TE2XXP and modems

[Joe Carroll]

We are doing something similar  today with successful phones, fax, and modem...   PURE TDM..  no SIP

Example Below....

PSTN ----<PRI(s)> ----  <Asterisk> ---------------- <Nortel PBX> ---- Phones, faxes or modems
                                                      |
                                                      |
                                                      |
                                                      |------------------ <Avaya PBX>---- Phones, faxes or modems

In fact, today's setup is :
PSTN ----<PRI> ----  Alcatel OXE PBX ---- Phones, faxes or modems

I'm wondering if inserting an Asterisk server between PBX and PSTN would break modems and faxes.
For phones, I'm confident it will work.
Any call that will cross Asterisk would be treated without any echo cancellation or codec translation.

So the main question is "is TE2XXP-enabled Asterisk able to switch TDM without introducing latency that would spoil modem or fax services ?".
