Hi, I m using asterisk on a system without a digium hardware, and when i try to use trunk=yes for my iax2 links, i just get this message while debugging: Tx-Frame Retry[000] -- OSeqno: 000 ISeqno: 001 Type: IAX Subclass: AUTHREQ Timestamp: 00006ms SCall: 16384 DCall: 16384 [192.168.1.1:4569] AUTHMETHODS : 2 CHALLENGE : 753310823 USERNAME : 350001 Rx-Frame Retry[ No] -- OSeqno: 000 ISeqno: 000 Type: IAX Subclass: INVAL Timestamp: 00000ms SCall: 16384 DCall: 16384 [192.168.1.1:4569] if i remove trunk=yes, it works, but i would like to run multiple channels at the same time. zaptel was compiled normal (make clean ; make linux26 ; make install) and ztdummy was loaded without problems (modprobe ztdummy) which also loads zaptel driver. Does anyone has this problem too and a hint to fix it? Regards, -=Raul=-
