Hello all,

Lately I faced an issue that Kamailio is not responding to some invite packets coming from SBC. When investigating I found that these packets exceeds MTU size.

Could this be the issue? Knowing that in Kamailio configuration I have a condition on is_method("INVITE"). Could be that in case of packet exceeding MTU size it’s not considered as invite packet by Kamailio?

I have Kamailio 5.2.5.

Regards,
