Hi Paul


I think it depends on the lines/ technology you get in the customer location
(eg:- PRI, ISDN, separate PSTN lines)

If you are getting separate pstn lines you can get a voip/pstn gateway like
"digium G400 VoIP Gateway" or "grandstream GXW4104/4108"

There are deferent options for other technologis if you go through digium
and grandstream web sites.

Subject: [AusNOG] VOIP PBX Analog card advice


Afternoon all, normally we provide SIP only PBX services for customers
however we have been asked to provide a SIP PBX with Analogue PSTN lines for
inbound and outbound calls.


We normally provide Elastix as a simple cost effective PBX for small
customers and in general it works well for what they need.

I am looking for some wisdom from people who have installed a decent 4 line
card for use with Elastix before quoting the customer as we had experience
some time ago with timing issues when using analogue cards with VOIP


Any suggestions would be appreciated.
