Hi serusers, Anybody has a sample ser.cfg that forward calls to Cisco AS5300 GW? I am using the Nathelper templet config file and got NAT +RTP relay works on IP2IP, but dont know how to work with PSTN through Cisco AS5300 GW. where to put the forwording code. I got some sample code here: # is it a PSTN destination? (is username nummerical and does not begin with 8?) if (uri=~"^sip:[0-79][0-9]*@") { # ... forward to gateways then; # check first to which PSTN destination the requests goes; # if it is US (prefix "1"), use the gateway XXX.XXX.XXX.XXX... if (uri=~"^sip:1") { # strip the leading "1" strip(1); forward(XXX.XXX.XXX.XXX, 5060); } else { # ... use the gateway YYY.YYY.YYY.YYY for all other destinations forward(YYY.YYY.YYY.YYY , 5060); } break; } I dont know if it can talk with Cisco 5300 GW though. Where should I put it in ser.cfg with NAThelper + RTPreply support? How to debug the ser.cfg, if i hear busy tone when i dial the PSTN number.
