Summary:                    [patch] After upgrading to asterisk 1.4.27 Optipoint
SIP phone can no longer register
Description: 
SVN revision 218578 (Send request contact header field with response to
registrer queries instead of the address of record) introduced a change in
the generation of SIP Contact-Header fields. After this change, my
Optipoint 400 SIP phone thinks it is not registered to asterisk, but
asterisk has a working registration.
In sip debug traces (attached), I see that 1.4.26 sends the Contact-Header
in the final REGISTER  response as "Contact:
<sip:13 at 192.168.50.254:5060;transport=udp>;expires=605" whereas 1.4.27
sends "Contact: sip:13 at 192.168.50.254:5060;transport=udp;expires=605" which
misses the angle brackets and seems to confuse the phone.

Reverting that one patch leads to a working 1.4.27 where Optipoint phones
are able to register again.
