Dear All, I'm using a2billing interface with asterisk in order to bill all calls flowing through my PBX... I need to prevent my customers to use the same extension from different IP addresses so I created a new extension under extensions.conf as follow: [michofr] type=peer username=michofr accountcode=4197464352 regexten=michofr callerid=111111 amaflags=billing secret=123456 nat=yes dtmfmode=RFC2833 qualify=yes canreinvite=yes disallow=all allow=ulaw allow=alaw allow=gsm allow=g729 host=192.168.0.164 context=a2billing regseconds=0 cancallforward=yes When trying to registr I'm getting 403 Forbidden...I think it's a domain issue under sip.conf file....Can someone help me in that please?
