Theorically (according to the LCR documentation), "to_gw()" must be
used when processing in-dialog requests. However I'm not sure of the
cause of your error, which is exactly the line 384 in your script?

Anyhow I suggest you a different approach:

- Set a different flag for each gw (in LCR 'gw' table) depending on
the sending socket that must be used.
- After calling 'next_gw()' inspect the value of the gw flags (stored
in a configured AVP) and choose which 'force_send_socket()' to use.
