Never quite got this. UDP packets can be up to 64k, right? And fragmentation is a standard IP feature if a packet is bigger than MTU size.

The customary inter-Kamailio solution is jumbo frames (if you control network end-to-end) or TCP.

Hi!
Was looking on some way to compress SIP signalling between internal servers. But found out, there are no some pre-defined or recommended mechanism of doing this. Yes, I found gzcompress module, but it will help only in case of big body, but not whole message itself. Like in some cases you can have 4-5 RR headers, which is already a lot of info.
What I googled is
- SigComp
- Compact Header form
As I found, SigComp is really not widely-used method and it support along opensource SIP servers/PBXes is not documented. For Compact Header form - is there any way of using Kamailio to compress message this way? Maybe also there is a way of having some intermediate proxy-layer software, that will gzip/gunzip SIP signalling in realtime?
All of this actually cause info in SIP/SDP grows rapidly, unfortunately MTU size is not. [image: Sent from Mailspring]
