[cisco-voip] International Calls Not Working for Remote Site

[Steven Sarte]

I have this remote site which is an extension of HQ.  This site does
not have a voice gateway so it uses the HQ voice gateway to make
calls.  The issue is they can't seem to make international calls,
local and long distance work fine.

Each site has its own device pool, region, and location.

The only thing I can think of it might be a codec issue.  The reason I
say this is because for the remote site it chooses G.729 for all
sites, even within.  (I know it shouldn't be this, I inherited this
VoIP environment).  For the HQ it has G.729 for all sites except
within, it uses G.711.  So as a temporary fix I configured the remote
site phone with the HQ device pool and works fine.

I did some testing and when a call is made from the remote site to the
PSTN it uses codec G.729 local and ld calls work fine but not
international calls.

Any help would be greatly appreciated.

Thanks,
Steven Sarte
