New Revision: 275308

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=275308
Log:
Fix port parsing in check_via.

If a Via header contained an IPv6 address, we would not properly parse
the port. We would instead get the information after the first colon in
the address.

(closes issue #17614)
