Hi,
I've reworked nua_stack_init_transport (from nua_register.c) to look for
multiple instances of NUTAG_URL and NUTAG_SIPS_URL in the tag list. The
old nua_stack_init_transport ignored all but the last instance of
NUTAG_URL and/or NUTAG_SIPS_URL.
This change makes the behaviour of nua_create consistent with the
documentation for NUTAG_URL and NUTAG_SIPS_URL.
Following is my implementation. I've tested it with NUTAG_URL, but I
haven't tested it with NUTAG_SIPS_URL. Could someone please have a look
over it?
Cheers,
--JT
