New Revision: 404592

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=404592
Log:
res_pjsip_outbound_registration: Add validation for 'server_uri' and 'client_uri'.

When applying configuration for outbound registrations the 'server_uri' and
'client_uri' fields were not validated. The code will now confirm that they
exist and that they contain parseable SIP URIs.
