[Freeswitch-users] new site, cant call OUT!

[Sean Devoy]

Thanks Ken,

 

I captured a siptrace and started pocking around.  Then I got logged into
the local lan (logmein).  The cisco router has multiple local ip addresses I
can login into - odd.  Then I noticed the Cisco (which is in Gateway mode)
has a WAN address of 10.1.10.10!!!  I poked around and found the Comcast
Business Router on the other side of the Cisco.  Yippee DOUBLE NAT.  I chose
to just say "NO."

 

Thanks for the answer.

 

Sean

Sounds like a possible NAT issue... But the only way to know that is look at
a sip trace and see whats going on that way and maybe even looking from the
phones perspective

Hi All,
 
(Git head build last week on centos 5.n)
 
This is a new one for me.  Calls IN to the new customer with Cisco phones
behind NAT are working, but not outbound!
 
I have not been to the site yet.  I am told that they can call out once or
twice then have to reboot the phone to dial out.  Dialing in continues to
work!  one person says the phone says "Call merged"  another says it say
"Request merged" on the phone display!
 
I did see in the logs, that when it works, we get:

Can anyone shed light on what's happening "at that particular juncture" and
how I may go about debugging it?
 
I was thinking FS was not finding a connection through NAT to phone, but
then why do incoming calls work?
 
Thanks in advance,
Sean
