Subscribe request offer with a=inactive

[Thomas de Rooij]

Hi all,
I'm facing an issue where a subscribe request (with flags 'all siprec') results in an SDP offer with one a=sendonly and one a=inactive. I'm issuing the subscribe request command immediately after the answer command (when processing the 200 OK). Could it be that the rtpengine has not yet received any packets from the calling party as the answer SDP has not yet reached the calling party? Hope that I'm just missing something small.

Kind regards, Thomas

The RTP reception state should not have any effect on what gets
advertised in the SDP. Could it be that the call you're subscribing to
has one-way media to begin with (i.e. one side recvonly, the other
sendonly)?

Feel free to post a concrete example from the debug log if you can't
figure it out.

Cheers
