[Asterisk-Users] Echo on internal SIP

[Philip Siegrist]

Hi All,

On my * server I am getting echo on internal SIP calls. I.E. Sip 2
Sip. Calls going over the T1 via the T100p are fine.

I have used ulaw and gsm, gsm has less echo but it is still noticable.
All phones are snom 190s.  Any ideas on what i can do to cancel this.

Thanks,
