[Asterisk-Users] Asterisk & Broadvoice Incoming Calls Problems

[Luis Jimenez]

Hi, i'm having problems with broadvoice incoming calls. I can perfectly place calls but my Asterisk Box is having problems when registering with the SIP Proxy. Sometimes it register and the call gets into asterisk, but without sound (seems to be NAT problems) and sometimes its not possible for asterisk to receive the calls. Everything was working great exactly for a month, but a week ago it crashed and stop working. I dont know if someting happened with the broadvoice service or the problem is mine, cause i tried with the same setup it was working.
Im behind a NAT Firewall, so i need a setup that can work in this condition. Here is part of my setup:

sip.conf
externip=200.42.xxx.xxx
nat=yes


register => 305xxxxx22 at sip.broadvoice.com:MyPassword1:305xxxxx22 at sip.broadvoice.com
register =>  305xxxxx66 at sip.broadvoice.com:MyPassword2:305xxxxx66 at sip.broadvoice.com
