Hi Juan Pablo,

usually this kind of fragmentation problems were an issue for UDP, but never found similar problem for TCP. Actually this the reason why the IETF guys want to obsolete UDP for SIP and keep only TCP...

how is generating the packages ? what device? because more or less it will responsible for framing the content.

Regards, Bogdan

Hi all,

We are having some problems with long SIP IP packets that are being fragmented.

We are using TCP as transport and packets bigger than ethernet MTU (1500) are being fragmented, but the "more-fragments" bit in IP flags is not being set. This is causing the remote gateway to timeout and close TCP session.

Have somebody come across this issue before? Any suggestions?

Thanks

Juan Pablo
