I just solved a similar problem on my asterisk box. i just enabled nat=yes
and removed the externip from the nat portion in sip.conf. Try it.

We have the latest version of asterisk, on a xeon dell server (2gb ram),
with 6 snom320's(latest firmware) and 3 grandstream gxp 2000's (latest
stable firmware) and are having a few problems. We have a basic menu that
transfers calls to different extensions. The problems can be found on all
extensions. We have 2 different incoming providers and the problem happens
on both providers.
I want your input on 2 problems, they are the following:
1.
60% of the time everything works fine and there are no problems, 40% of
times when the calls are transferred to an extension, after a few seconds ,
the call drops. The log from the server is below(this is from pickup to
hangup, the main area of concern is where it says warning).

2. When a call comes in or is transferred(not on outgoing), there is a
delay until the person on the incoming line can hear you. We can hear them,
but they can't hear us. Sometimes there is no delay, sometimes for person
calling in cant hear you for 6 seconds.
Thanks for the help in advance!!!
