HI. I have problems from incomings calls when I use in sip_nat.conf
the following:
with this no incoming calls passthru it sound busy for the caller to pbx
nat=yes
localnet = 192.168.2.0/255.255.255.0
externhost = 198.121.47.130
but with externhost= it works fine just like this config below
nat=yes
localnet = 192.168.2.0/255.255.255.0
externhost = mypbx.no-ip.net
NOTE
I had edited etc/hosts
adding the dynamic domain as below
hosts
Do not remove the following line, or various programs
that require network functionality will fail.
127.0.0.1 localhost
127.0.0.1 mypbx.no-ip.net
127.0.0.1 pbx.localdomain pbx localhost.localdomain
I have 2 routers before my pbx box.
1 router has sip ports 5060-5070 udp and rtp 10000-20000 udp forward to second router ip
2 second router has sip ports 5060-5070 udp and rtp 10000-20000 udp forward to pbx box
I need to use externip= instead of externhost= cuz i have problems with 1 audio side problem for a remote extension
and is recommended to use externip=
I have talk with support from my sip DID and they did a trace
they said that when it is set to public ip (i suppouse they refer to when i put externip=) they saw that the the user is not comming in the INVITE and therefor the call is blocked
so i dont know what is the problem when putting externip= and I can not make fix the 1 audio problem from a remote extension e63 nokia
