I'm having a problem reassembling UDP packets on my Asterisk servers after passing through Kamailio (it appears to me an OS level issue, nothing to do with Kamailio).  Is there a way, with Kamailio, to limit the size of a SIP message?  I know I can just start removing headers, but that doesn't seem like a realistic solution.  I see that Kamailio can compress the message body, but can Asterisk handle that?  How do other people handle this?
