[Freeswitch-users] How to set user in contact header on b-leg for external gateway?

[Seudin Kasumovic]

As I can see (in sofia_glue.c)  invite_contact is set from channel variable
sip_contact_user if empty. I export channel variable sip_contact_user in
dial plan, but on b-leg steal see Contact: <sip:auto_to_user at 1.2.3.4:5060
;transport=udp;gw=mygw>.
Seams that sip_contact_user is used for a-leg only.

Gateway has set param

<param name="extension" value="auto_to_user"/>

In sofia.c 'auto_to_user' or 'auto' value in extension affects only
destination_number.

So, I can't see any way to set contact header user name for outbound calls
for gateway.
