[Serusers] ser, pstn gateways

[Jev]

Hello all,

Im using ser, with esteras softphone, and a couple of cisco ata186's. I 
have to say I really like ser, as it is small fast, and reliable without 
being over complicated.

I would like to know what other ser users and developers use for pstn 
gateways? I have a openline4 card from voictronix, but there is no 
software support for sip (When I bought it I thought I would use h.323).

I have looked at cisco's pstn gateway modules, but was turned off them 
because of price, and lack of clear straight forward information to name 
but two reasons.

Ideally what I would like to have is a solution that would support at 
least 4 pstn lines (expandable to maybe 8), that would run on FreeBSD 
(or at worst linux), works well with sip & ser, with high quality audio, 
and minimal delays when dialing in out.

TIA,
-Emil
