Summary:                    [patch] parsing of sip register lines is broken
Description: 
A register line within sip.conf has the following format:

[transport://]user[:secret[:authuser]]@domain[:port][/extension][~expiry]

To extract the extension the parser is searching for '/' in the whole line
(from right to left).
As [/extension] is optional this causes trouble if there is no extension
defined and [transport://] is set.

Suggested solution: parse extension and expiry after the last '@'
character.

A backport to affected older versions would be appreciated.

  parsing extension correctly from sip register lines
  
  If a transport type was specified, but no extension, parsing of the
extension would return whatever was after the transport rather than
defaulting to 's'.
