I have a FreeBSD router installed with Asterisk 220.127.116.11.1 (from the ports),
this system is using by 180 SIP accounts but i get the message from “sip set debug” on many SIP phones :
<— Transmitting (NAT) to 10.10.207.102:5060 —>
SIP/2.0 481 No subscription
I can’t find any forum post about this problem, does anyone know what is wrong with it?
