Grandstream GXP2140 can't make calls

[arri...@gmail.com]

Just got a Grandstream GXP2140 and for some reason it cannot make calls.  Cisco SPA525G and Zoiper on the same account can make calls without issue.  Invites from the Grandstream never seem to make it past kamailio.  Nothing on freeswitch, nothing in kazoo logs.

Kamailio log:

Ironically your issue is the same as the previous email just posted to this list.

There is a setting called “Send <something> with OBP” or “Send Route with Outbound Proxy” or something like that in the Grandstream interface. Turn it off.
