Hi... First I try MediaProxy, but it has problems with multipart SDP packets... It LOGs: error: mediaproxy/checkContentType(): invalid Content-Type for SDP message error: mediaproxy/getSDPMessage(): content type is not `application/sdp' error: use_media_proxy(): failed to get the SDP message Then I try RTPProxy... but it also didn't work. It gaves me: ERROR:check_content_type: invalid type for a message ERROR: extract_body: content type mismatching ERROR: force_rtp_proxy2: can't extract body from the message We are using a Cisco 2600 for IPIPGW (our PSTN GWs are on the H323 side). This messages appears for any call destinated to PSTN. Can anybody point me how to solve this problem? The solution based on MediaProxy had worked until last month... Edson.
