### Description

When using dispatcher module to select destination we didn't configure explicit port:

``` sh-4.1# cat /etc/kamailio/dispatcher.list # $Id$ # dispatcher destination sets #

# line format # setit(int) destination(sip uri) flags(int,opt) priority(int,opt) attributes(str,opt) 1 sip:127.0.0.1 0 0 ```

When we try to rewrite port in R-URI as in following configuration:

``` sh-4.1# cat /etc/kamailio/kamailio.cfg #!KAMAILIO #

debug=3 sip_warning=yes port=5060

mpath="/usr/lib64/kamailio/modules/"

loadmodule "pv.so" loadmodule "xlog.so" loadmodule "dispatcher.so"

modparam("dispatcher", "list_file", "/etc/kamailio/dispatcher.list")

route { ds_select_dst("1", "4"); xlog("will update <$ru>"); xlog("changing $rd to $dd\n"); $rd = $dd; xlog("changing $rp to $dp\n"); $rp = $dp; xlog("final RURI is <$ru>"); exit; } ```

Kamailio crashes on line: ``` $rp = $dp; ```

Interesting thing is that we get port on previous line (see attached log).

### Troubleshooting

#### Reproduction

Use provided configuration and dispatcher.list file and send any SIP request message to Kamailio.

#### 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.

#### 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). -->

``` INVITE sip:B@127.0.0.1;user=phone SIP/2.0 Content-Length:0 From:sip:A@127.0.0.1;tag=13X72gb4A0gYZBa5 To:sip:B@127.0.0.1 Via:SIP/2.0/TCP 127.0.0.1:5060;branch=z9hG4bKZ2a_U73e_8Z7Be26 Call-ID:8EFCC0126CBA18AF6D6ECE17@4742ffffffff CSeq:1 INVITE Max-Forwards:60 Contact:sip:127.0.0.1:5060;transport=TCP

```

### Possible Solutions

<!-- If you found a solution or workaround for the issue, describe it. Ideally, provide a pull request with a fix. -->

As a workaround all dispatcher module entries need to have explicit port configured.

I have used official packages for CentOS 6 for Kamailio 5.3.3. I was able to reproduce it on Kamailio 5.2 also.
