Description (partial)

Phone closes it video decoder if the other party advertises dynamic RTP payload type.

From logs we can see the following:

02:04:27:28.622 - I/ACCU: accu_sccp_ep_evthd(). id=83(flow_ctrl_notify), size=32 
 02:04:27:28.623 - I/ACCU: accu_sccp_ep_proc_tsinfo_flow_ctrl_notify 
 02:04:27:28.623 - I/ACCU: accu_term_event. [E1 L3]. event=tsinfo_flow_ctrl_notify. state=CONNECTED 
 02:04:27:28.623 - E/ACCU: accu_sccp_line_term_tsinfo_flow_ctrl_notify(). close video decoder 
 02:04:27:28.623 - I/ACCU: accu_term_event. [E1 L3]. event=tsinfo_close_multimedia_recv_chan. state=CONNECTED 
 02:04:27:28.623 - I/ACCU: accu_term_pend_evt_cfg(). none->tsinfo_close_multimedia_recv_chan 
 02:04:27:28.624 - I/ACCU: accu_sccp_ep_evthd(). event=106(monitor_create)

8945 phones doesnt support Flow control Notify. For example in a video call if the other party sends a different payload type (PT102), 8945 will not accept it and close its video decoder
