[asterisk-users] TDM cards

2020-02-16 Thread Dovid Bender
Hi,

It's been forever since I dealt with POTS lines. We have a client that
needs FXS and FXO support. If memory serves correct we used the TDM400P
with fxs_gs/fxo_gs. What's the equivalent of that card today?

TIA.

 Digium, Inc. Wildcard A4B 4-port analog card (PCI-Express)

I'm still PO'ed that I had to buy an expensive new card when my old TDM400
was working perfectly well, but the DAHDI drivers no longer support it.

It is µ-law by default, but you can override it in the dial string¹. 
Note that if you do override it, you would need to use a codec that has 
a static RTP payload code² as no SDP is exchanged.


Kind regards,
Sean
