Hey Guys,
I was wondering if someone can help me with identifying my issue (which
I suspect it as a bug).
I am doing some redirect tests between 2 servers, both running same
Kamailio version - 4.0.0 out of debian packages.

On redirect server I have location stored, doing lookup and right after
using "sl_send_reply("302", "iClass4-AP Redirect");"
Up to information stored in the Contact of redirect request everything
works smooth, the problem which I get is with the information in the
Contact of the redirect:

"""
It appears that the information of the first contact is correctly
encapsulated but the second (out of first branch) not.
Due to this in the server capturing the redirect I will only have first
contact correctly written in the ruri and second one partially. Example
of loging this:
"""

Extracted destination set: Contact: <sip:dan@10.10.10.154:5060>;q=0.01,

ru: sip:d...@iec.itsyscom.com, du: sip:127.0.0.1:5070

""".
I would suspect the redirect function not properly inserting the content
of each contact uri within it's own <> boundaries but I would appreciate
a confirmation on this from someone more experienced with Kamailio's code.
Thanks in advance for any tip!
