[SR-Users] Path and DNS SRV

[Klaus Darilion]

If the add the Path header manually, then it is not seen by the 
registrar/usrloc module, asthe header will only be added when generating 
the "to be forwarded" message - and this never happens as the message 
terminates on the registrar. You could try msg_apply_changes() after 
adding the Path header.

Klaus
