[Asterisk-Users] Please help - jitter problem

[Leon Botes]

I have a hard phone on my lan behind my nat gateway. I program it to dial
out via iconnect.
Works great no jitter.

When I set * to use that same iconnect account I get lots of jitter.
My * is on the same lan as the hardphone using same gateway.
I have set the asterisk codecs same  as what my hardphone uses.

Please anyone with suggestion would be appreciated. I am getting desparate
here.

Redhat 9, * 1.0
