Dear all,

I have enabled stun module and configured it in asterisk , but asterisk not using stun returned public ip address for any of the sip requests going out of my network.

i have done settings as below

res_stun_monitor.conf settings:

[general]
stunaddr = stun.ideasip.com stunrefresh = 30

stun show status Hostname Port Period Retries Status ExternAddr externport stun.ideasip.com 3478 30 3 OK 61.12.17.171
39710

sip.conf localnet2.168.0.0/255.255.255.0
register=>jai9999:123456:jai9999@sip2sip.info/jai9999

when above command runs , it is sending register method with my private ip address.

REGISTER sip:sip2sip.info SIP/2.0

In above packet VIA and CONTACT SIP-HEADERS contains the asterisk server private IP address which is behind the NAT , as per my understanding it supposed to be the public ip address of my network.

is this the expected behavior of asterisk while stun is enabled

Thnaks in advance

Thanks & Regards Shivakumar
