Hello, unfortunately no one answered til now. So i ask a bit different: 1. Is it possible to create a call to a SIP device where i can define the MessageBody or SDP field on my own (as mentioned in first mail)? I want to INVITE one sender (plays an announcement) and many receivers. These INVITEs should be independent, so if one receiver is out of order all others can be announced anyway. 2. Is it possible to invite a SIP device independend from others? I tested: pacall device1; pacall device2; uuid_bridge sip_uuid1 sip_uuid2 -> this is a little bit sick, i know ;) originate sofia/domain/device1 device2 -> but this works only with 2 devices AND the INVITEs go out successively Has this "media" command anything to do with it? Hope this clears more my problem.

Here comes scenario: - one sender device that sends multicast RTP stream to network - one or more receiver devices that only receive RTP data from network The codec is a proprietary one (41), freeswitch can ignore all RTP data. Sender has to get attributs: u=file:/C:/dap/123.wav c=IN IP4 239.194.0.14 t=0 0 m=audio 7280 RTP/AVP 41 a=rtpmap:41 PCMA/16000 a=recvonly b=AS:128 Receiver has to get attributs: c=IN IP4 239.193.201.69 t=0 0 a=specialExtension:2 a=type:broadcast m=audio 7280 RTP/AVP 41 a=rtpmap:41 PCMA/16000 a=sendonly Is it possible to use freeswitch API to do this? Many thanks in advance, Thomas Sluschny
