Hello all,
I figured it out.
The heplify-server truncates the packets above 8192 bytes, I changed the
code of heplify-server and it is working.
This question is not related to kamailio, so I will open an issue on
heplify-server.
Thanks.

Hello all,
I am using the siptrace module on Kamailio 5.3.5 and I am trying to
monitor the SIP over websockets traffic with Homer 7.8.1 (heplify-server).
I notice a strange behavior, some packets are not presented on Homer.
I checked heplify-server and i notice the next warning:
heplify-server: 2020/07/22 18:41:09.425513 decoder.go:103: WARN HEP packet
length is 8192 but should be 11663
So I think the packets are truncated by 8192 (packet size), so they are
ignored by heplify-server.
I have done a tcpdump on the Homer machine and have the next output, where
I can see some packets with size greater than 8192.

Can you guide me to identify where the packets are truncated?
