[Freeswitch-users] Special SIP scenario

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.

Betreff: [Freeswitch-users] Special SIP scenario

Hi all, 

I want to do a special SIP using and I dont know how to configure it
with: originate/bridge/transfer no_media and so on 
May be it is not possible with freeswitch? 

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: 
c=IN IP4 
t=0 0 
m=audio 7280 RTP/AVP 41 
a=rtpmap:41 PCMA/16000 

Receiver has to get attributs: 
c=IN IP4 
t=0 0 
m=audio 7280 RTP/AVP 41 
a=rtpmap:41 PCMA/16000 

Is it possible to use freeswitch API to do this? 

Many thanks in advance, 
Thomas Sluschny
