<pre wrap="">If your useing 0.8.11, I think you can just do a few google searches and
you will find a function that does this.

I believe you can do this a lot easier in ser.cfg 2.x using selects to pick
the Contact.

Juha,
I'm new into C programming. Could you kindly let me know where this code
should be inserted?
yes, i implemented a function called move that turned 302 to invite, but
that code relied on a patch to tm module that gave me access to contact
header of reply in reply route.
i found the function and it is below. someone who needs this
functionality has to check if same kind of access to the contact header
of the reply is still possible or if the access method is now different
and modify the code accordingly.
also, all contacts would need to be taken from 302, not just the first.
contact_re was compiled during module initialization:
regcomp(&contact_re, "^Contact:(.*)$", REG_EXTENDED|REG_NEWLINE);
needless to say, i'm not proud of this code, but it gives an idea on how
it can be done.
