Later, when I use branching (with q=-1.0), the kamailio sends an invite to only one AOR from 7777 at 172.17.0.252:5062
If I use another Sip client without "instance" , such as Linksys-PAP2T, branching works fine.
GRUU is always disabled

### Troubleshooting
#### Reproduction
<!--
If the issue can be reproduced, describe how it can be done.
-->
#### Debugging Data
<!--
If you got a core dump, use gdb to extract troubleshooting data - full backtrace,
local variables and the list of the code at the issue location.
gdb /path/to/kamailio /path/to/corefile
bt full
info locals
list
If you are familiar with gdb, feel free to attach more of what you consider to
be relevant.
-->
```
(paste your debugging data here)
```
#### Log Messages
<!--
Check the syslog file and if there are relevant log messages printed by Kamailio, add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site).
-->
```
(paste your log messages here)
```
#### 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).
-->
```
(paste your sip traffic here)
```
### Possible Solutions
<!--
How can I disable GRUU support completely?
