[pjsip] Send out multiple audio streams

I am trying to figure out how to send out multiple audio streams when
making a call between two PJSIP clients. The goal here is to have N number
of separate audio streams that will be mixed on the other client.
I am setting the pjsua_call_setting config to aud_cnt 2 and I can see in
the incoming INVITE on the callee side two m lines:
Media Description, name and address (m): audio 65217 RTP/AVP 109 18 8 0 96
Media Description, name and address (m): audio 60821 RTP/AVP 109 18 8 0 96
On the INVITE response, the callee populates only one m line:
Media Description, name and address (m): audio 56863 RTP/AVP 109 96
Suppose I want to play, from the caller side, a wav file on each of the
streams- how can I play a file on a specific stream? The only way I've been
able to send out the wav files is by using pjsua_conf_connect(), but in
that case they will of course be mixed together.
I am trying to get this done using the PJSUA API.
