jonastelzio created an issue (kamailio/kamailio#4349)
### Description
<!--
Explain what you did, what you expected to happen, and what actually happened.
-->
Kamailio configured with the following listeners:
```
listen=udp:LOCAL_IP:5060 advertise DNS_HOST:5060
listen=tcp:LOCAL_IP:5060 advertise DNS_HOST:5060
listen=tcp:LOCAL_IP:5061 advertise tls:DNS_HOST:5061
```
Notice `tls:` in the advertise part of the last listener. TLS Termination
happens upstream by, in this case, haproxy.
The following happens:
1. Kamailio receives invite from a phone via TCP, on the TLS advertised
listener. The phone is communicating via TLS, but it's terminated upstream.
2. Dispatcher is used to select where to forward it
3. Forwards via UDP and the call is connected downstream.
4. The downstream asterisk ends the call by sending a BYE request
5. Kamailio receives this, and generates a BYE request for the phone.
The generated BYE request has an incorrect Via-header:
`Via: SIP/2.0/TCP
jswiatek.dk.office.tlz:5060;branch=z9hG4bK2e8f.2625efdb2ab26c466f55b8baf1bf807d.0`
This should be `SIP/2.0/TLS`, and the host should be `:5061`
In the provided PCAP, this is message is message number 15.
A similar issue was addressed in this commit:

### Troubleshooting
#### SIP Traffic
<!--
If the issue is exposed by processing specific SIP messages, grab them with
ngrep or save in a pcap file, then add them next, or attach to issue, or
provide a link to download them (e.g., to a pastebin site).
