[Asterisk-Users] echo problem

[trixter http://www.0xdecafbad.com]

I have searched for how to locate echo cancelation on SIP clients, but
cant find anything and echocancel=y doesnt seem to have any effect.

Configuration:
CVS-HEAD from last month
iPAQ h5500 with SJPhone (gsm/ulaw/alaw)

Problem description:
When I place or receive a call I hear a faint delayed echo of myself.
The other party hears a really bad nonmuted echo that makes the call
unusable.

Aside from the voip-info page on echo cancelation, can anyone suggest
directives for sip.conf or similar to play with for echo cancelation.


I have looked into sjphone as the cause, after speaking with developers
there it was suggested to see if my asterisk box is the cause.  

Any suggestions?
