Hi... We are trying to use a Cisco 2600 as our IPIP-GW between our SIP and H323 networks. Until a week or so the comunications were working so-so, but from a week it stops completely. Digging on the problem, I found MediaProxy messages informing that it couldn't handle the SDP informations, that SDP was illegal... Looking on Google I finded that this behavior was reported as a know limitation of MediaProxy and NAThelper modules (http://lists.iptel.org/pipermail/serusers/2006-June/028981.html). Aren't this limitations resolved on Mediaproxy 1.8.2? What are our best choises? Maybe migrating to Yate? Thanks for any thoughts... Edson
