### Description
Kamailio cannot parse Via header with full IPv6 address. And generate errors like ``` ERROR: <core> [core/parser/msg_parser.c:340]: parse_headers(): bad header field [Via: SIP/2.0/TCP [2a00:1370:8131:ffdf:4398:8903:f613:58b6];branch=z9hG4bK02cc.edc691e200000000000000] ```
#### SIP Traffic
OPTIONS messages cannot be parsed ``` OPTIONS sip:example.com:5080;transport=tcp SIP/2.0 Via: SIP/2.0/TCP [2a00:1370:8131:ffdf:4398:8903:f613:58b6];branch=z9hG4bK0241.2e5db116000000000000000000000000.0 To: sip:example.com:5080;transport=tcp From: sip:proxy@example.com;tag=ecfe220eb77cee2ab0369a33b85d6b69-54b37dee CSeq: 10 OPTIONS Call-ID: 0d2146aa2a479f0d-2232@192.168.1.6 Max-Forwards: 70 Content-Length: 0 ```
OPTIONS messages parsed successfully. ``` OPTIONS sip:example.com.com:5080;transport=tcp SIP/2.0 Via: SIP/2.0/TCP [2600:1f1c:6d5:aa00::6];branch=z9hG4bK67a6.b0578ab2000000000000000000000000.0 To: sip:example.com:5080;transport=tcp From: sip:proxy@example.com;tag=c9c2897ae0601f24edc14b3f5f65b7e4-02fff025 CSeq: 10 OPTIONS Call-ID: 3555c29958953393-581752@3.101.84.6 Max-Forwards: 70 Content-Length: 0 ```

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 ```

Maybe it is something else in your config or another (custom) version.
Closing, it couldn't be reproduced.
Closed #2898.
Thanks, Daniel @miconda I will collect more debug logs and provide them here later.
