[Asterisk-Users] Echo X100P and X-Lite SIP Phone

[Jonathan Tew]

We're using an X100P card to connect to the SBC PSTN and have a SIP 
client (X-Lite) configured.  I'm using a headset (Plantronics 20) to 
connect to my computer.  When I first make a call to someone over the 
PSTN I can really hear myself echo bad in my headset.  As the call goes 
on it gets better and eventually doesn't annoy me.  Any ideas what this 
is or where to start trouble shooting?

When we talk SIP to SIP via Asterisk it works beautifully!

Any suggestions or pointers are greatly appreciated.
