### Description
Kamailio cannot parse Via header with full IPv6 address.
And generate errors like
```

New subject: [kamailio/kamailio] cannot parse IPv6 Via (Issue #2898)
It works for me with Kamailio master branch injecting the OPTIONS to the network using
protoshoot from the same source tree:
```
./misc/tools/protoshoot/protoshoot -f /tmp/options.sip
```
The debug messages are:

Maybe it is something else in your config or another (custom) version.
