Hi Derrick,

if you use a 3.x version, try t_relay_to (from the tm module docs):

1.5.37.  t_relay_to(proxy, flags)

   Forward the SIP request to a specific address, controlling internal
   behavior via flags.
...
     * flags - bitmask integer value to control the internal behavior.
       Bits can be:
          + 0x01 - do not generate 100 reply.

Cheers,

Henning
