Summary:                    [patch] IPv6 - Potential issue in via header parsing
Description: 
14223                 c = ast_skip_blanks(c+1);
14224                 if (strcasecmp(via, "SIP/2.0/UDP") &&
strcasecmp(via, "SIP/2.0/TCP") && strcasecmp(via, "SIP/2.0/TLS")) {
14225                         ast_log(LOG_WARNING, "Don't know how to
respond via '%s'\n", via);
14226                         return;
14227                 }
14228                 pt = strchr(c, ':');


Seems like we're looking for the first colon.

Via: SIP/2.0/TCP
[2620:0:2ef0:7070:250:60ff:fe03:32b7]:5060;branch=z9hG4bK4882ebf2298267bc4ba97d222289760c.1;rport


In this case, port would propably be 0 and not 5060...

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.
