6630 - Video Call - DTMF
I am currently testing the 6630 video calling capabilities and I found out that (unlike all other brands) this device DO NOT send DTMF indication during VideoCall (3gpp-324m).
We have tested with all kind of InputIndication capabilities in the TCS but didn't have any luck
Is this a known problem? Are we messing up anything?
I just started with checking available APIs. Were you able to establish video call? What API can be used for it?
Are you using AT commands to set up the video call? If so, which commands are you using and where can I find a specification of commands for video?
