[SR-Users] Trunk between Asterisk and Kamailio problem

Hi list, I have this structure IP Phones -> Asterisk Client (LAN) -> (router) -> Kamailio/RTPproxy(Internet) -> Asterisk (local from Kamailio) -> Trunk SIP/Pstn All is working well, I don't have problems with NAT and I managed about 6000 daily calls. For a couple of months I've the next problem.The problem is that in the Asterisk randomly received this message. [Sep 29 04:04:29] NOTICE[3393] chan_sip.c: Peer 'kamONOp' is now Lagged. (2075ms / 2000ms) [Sep 29 04:04:41] NOTICE[3393] chan_sip.c: Peer 'kamailioONO' is now Reachable. (1888ms / 2000ms) In some Asterisk Client I get this message 10 times in a hour, and usually coincide with periods of high load on the kamailo. Also I am getting these messages in the log of Kamailio: Nov 11 08:59:53 c1 /usr/local/sbin/kamailio[8079]: INFO: <core> [forward.c:788]: broken reply to forward - no 2nd via Nov 11 08:59:53 c1 /usr/local/sbin/kamailio[8082]: INFO: <core> [forward.c:788]: broken reply to forward - no 2nd via Are these two issues related? Whay can I do? Kind Regards SiscoCS (Sorry for my english)
