Hello, I tried Kamailio 1.4.1+TLS with Mediaproxy 2.1.0. Everything works fine, but when I place call to Hold (using Hold button), Kamailio sometimes crashed. When I disable mediaproxy, Kamailio works without crash. I tried using engage_media_proxy() without any end_media_proxy or use_media_proxy and I also tried using use_media_proxy and end_media_proxy without engage_media_proxy with that same result. Sometimes Kamailio crash after first place call to hold, sometimes crash after few place call to hold/unhold. Sometimes work fine. OS is Debian Etch. Kamailio generate core dump.

Core was generated by `kamailio'.
