[Linphone-users] multicast RTP stream opened multiple times

[Christian Spielberger]

Hi,

I did a lot of tests with multicast early media.

Configuration on sender:
linphone_core_set_audio_multicast_addr(_lc, "239.1.1.1");
linphone_core_enable_audio_multicast(_lc, true);

also for the call:
linphone_call_params_enable_early_media_sending(cp,TRUE);
...
LinphoneCall* c = linphone_core_invite_address_with_params(_lc, a, cp);



On receiver:
linphone_core_accept_early_media_with_params(_lc, call, ncp);


Then start call to first destination and a second call to second destination.

The Problem:
For the second call a second audiostream to the specified multicast ip with new
port number is created. I would expect that the SDP for the second INVITE
reports the same port number like for the first INVITE and that for the second
call no further audiostream is created.

Currenlty, the multicast implementation in linphone seems to be senseless.

What has to be done?

Regards, 
Christian.
