The primary goal for me would be making the phone
activate its
microphone and speaker, so that the associated RTP stream would carry
valid Uplink voice frames. I assume sending a CC SETUP message and
pressing the green button on the phone would be enough for that. The
subsequent Alerting and Connect messages from the MS can simply be
ignored for now.
Per the protocol, CONNECT from MS to network needs to be followed by a
CONNECT ACK from network to MS. Are you sure that your test phones
will turn on their full audio path without that CONNECT ACK?
