[sr-dev] [kamailio/kamailio] sdpops: cannot parse big SDP (Issue #4000)

15 Oct 2024

### Description

Cannot be parsed `$sdp(body)` when received to big SDP.

### Troubleshooting

#### Reproduction

To reproduce you can use minimal config like
```
listen=tcp:127.0.0.1:5060

loadmodule "xlog.so"
loadmodule "pv.so"
loadmodule "sdpops.so"

route{
        xerr("SDP: TEST $tu\n");
        xerr("SDP: $sdp(body)\n");
        drop;
}
```
And send an INVITE message like in the attached file. In my case, the SDP size is 8710.

#### Log Messages

```
```

#### 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

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