Brekeke deletes last lines of INVITE message

Post by loop »

1. Brekeke Product Name and Version: SIP Server 3.7/466

2. Java version:1.8.0_144

3. OS type and the version: Windows 10

4. Your problem: Brekeke deletes last lines of INVITE message.

I want to make call with TLS and SRTP. There are two phones and one of them is behind NAT. So, I use TURN and STUN servers for IP resolution.
When I make a call, the INVITE message involves 6 candidates in SDP.


Created INVITE message:

I can see the same INVITE message on Brekeke Server computer with Wireshark. But when I look at the Brekeke log file, Brekeke gets broken INVITE message(last two candidate lines are missing).


The broken message from Brekeke log file:

Then, Brekeke modifies(removes last candidate) and sends the broken packet to the other endpoint.

Is this a bug or I am doing something wrong?

Hi loop,

Add the line below in the [Configuration]->[Advanced] page, and restart the Brekeke SIP Server.

Code: Select all

net.sip.packet.reader = false
The developer fixed this bug already so upgrading the SIP Server to the latest version will also fix the issue.
