Same problem here: if call come over ISDN PRI and it is for a SIP phone that equals to strong echo situation, at the SIP end. Interestingly this doesn't happen on all calls but it does on 95% of them. Asterisk load at that moment is insignificant - 1 to 2 calls.
I have tried with all possible echo cancellers in zconfig.h, with and without MMX, and with and without CFLAGS+=-march=i686 in zaptel Makefile, but without any success.
TE110P is on its own interrupt - no other cards on board except Intel chipset PCI LAN card (on shared interrupt) and machine is Intel 685 chipset based, with P4 Celleron 2.6 GHz, 1Gbyte RAM, WD 10K RPM IDE HDD.
I have even contacted Digium support with this issue, but except a request for some additional explanations of my setup, nothing from them so far (for about a week).
Anyone have an idea, why this type of echo happens ? As far as I have read on the lists this type of echo should not occur at all, but it simply does !
I consider all this MMX stuff to be voodoo for echo problems.
If you have a PRI and SIP phones then the echo occurs on the far end analog phone.
/etc/asterisk/zapata.conf:
echocancel=yes echotraining=yes or 600 or 800
Yo have to STOP and restart Asterisk for changes in /etc/asterisk/zapata.conf to take effect. You can unload chan_zap.so and reload it as well, but wby bother.
