[Freeswitch-users] extension-in-contact problem

[François Delawarde]

Hi Anthony,

My objective was just to test that feature in case it could come handy
with broken providers as you mention.

Looking at SIP traffic, the contact is mirrored correctly, as the "gw="
parameter is present in both cases:

- without "extension-in-contact":
INVITE sip:gw+sol_account at 192.168.10.80:5060;transport=udp;gw=sol_account SIP/2.0

- with "extension-in-contact":
INVITE sip:test at 192.168.10.80:5060;transport=udp;gw=sol_account SIP/2.0


So there might be a bug in "sofia_glue_find_parameter" (also used in
other parts of sofia.c), as it doesn't seem to find the "gw=" that is
present in the siptrace.

Tell me if I should add a Jira issue.

Thanks,
François.
