### Description
If the SIP request URI has a parameter ;user=phone, then the match with `myself` fails with error in log.
### Troubleshooting
Sending an OPTIONS request through the proxy:
``` OPTIONS sip:+358removed@example.com;user=phone SIP/2.0. ... From: sip:+358removed@example.com;user=phone;tag=JJhksk01ou7PFTq8xz1-GlhgGNG-c94A. To: sip:+358removed@example.com;user=phone. ... Content-Length: 0.
``` Note: The R-URI does NOT match myself. It never does in my case unless it's an attacker.
#### Reproduction
My config is very simple in terms of aliases:
``` auto_aliases=no alias=172.29.1.21:5060 ```
and in routing block:
` if (uri==myself) return;`
Log shows:
``` Listening on udp: 172.29.1.21 [172.29.1.21]:5060 Aliases: *: 172.29.1.21:5060
... 7(20681) ERROR: <core> [core/resolve.c:1808]: str2ip6buf(): invalid name, no conversion to IP address possible ... ```
### Possible Solutions
Sorry, I couldn't figure out where in the source this call to resolve.c functions happens.
