### Description
<!-- Explain what you did, what you expected to happen, and what actually happened. -->
### Troubleshooting
``` -->sip invite t_suspend() nats publish--->routeserver <---route result t_continue() but kamailio crash ```
#### Reproduction
<!-- If the issue can be reproduced, describe how it can be done. -->
``` wget http://220.231.180.131:12295/kamailio-nats-routeserver.tar.gz nats_url: nats://127.0.0.1:4222 start kamailio go run routeserver.go uac sip call kamailio, and kamailio crash ```
#### 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). -->
