Hello Daniel
Thanks for pointing out to the SIP traces. I found out that it if the
request is to be sent to a destination using a port other than 5060, it is
required to add the $uac_req(ouri) parameter too:
$uac_req(ouri)="sip:" + $var(asterisk_ip) + ":" + $var(asterisk_port);
....
$uac_req(ouri)="sip:" + $var(asterisk2_ip) + ":" + $var(asterisk2_port);
Thanks!
