Hello List, basically I want to know if there is any possibility to set the media attribute inactive/sendrecv in SPD. If there is any command I can use, or something else. Thank you.

Therefor I used WireShark to to find that the native phones send an INVITE to the PBX, for the party to go on hold, with media attribute inactive. Now, if I have a call between a FreeSWITCH user and a native phone, how can I make FreeSWITCH to make the PBX put the phone on hold? Somehow send that INVITE by command or any other methods. Thank you.
