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 handsets.
Any suggestions would be appreciated.
