Good day all
I cant get my grandstream bt-100 to register
My asterisk is on a public ip and the phone behind a nat firewall
I added nat=yes in sip.conf and did this on my grandstream
set the GS to "SIP server=asterisk.yourhost.com" and leave
"Outbound
Proxy" empty
* set the GS to SIP port 5060 and RTP port 5004 (and "Use random
port=No")
* set the GS to "NAT traversal=Yes" with "STUN
server=stun.xten.net"
* arrange port forwarding on your NAT router for tcp/udp 5062 and udp
5004 to your GS phone's IP address
* enter "nat=yes" and "canreinvite=no" in your sip.conf
for this GS
phone user
* in this order: issue a "reload" in the Asterisk console, restart
your NAT router and reboot the phone
*
* Please Help
