Keeping dialpad active during calls (enabling more options for server-defined features like call conference)

[GoogleCodeExporter]

I'm happy that the new revisions of Sipdroid works fine with my Asterisk
Servers, now I'm trying to add features like call forwarding, number
screening, etc. I seem to have met a dead end when I try to implement call
conference in Asterisk, because I can't press any keys during calls.

You see, the template algorithm for call conferencing requires the
conference host to press key1 during an active call to create "conference
room" and immediately inviting the person you're talking to, while placing
him on hold and getting a new dialtone, and after making a second call,
pressing key2 will invite the new callee and getting another new dial tone
to repeat the same process to add multiple conference members, and then
key3 to go the conference room yourself to start the conference, but this
can't be done by Sipdroid since there's no way for me to dial any keys
during an active call, unlike most other softphones which have their
dialpads always up in front of you.

Most server-based features are implemented by using dialed numbers as codes
to be parsed in order to execute particular server-defined commands, such
option is great for users to utilize features before or during an active call.

All you need to do is press menu. Then select option "Send DTMF".

ohh, so that's what it's for, thanks a lot. It's just sad that I still couldn't
implement my Asterisk call conferencing right. I don't know if it's because 
Asterisk
couldn't parse key codes when there is an ongoing call the same way through 
dialing
it during standby, or the way the number was dialed is just different if its 
done
during an ongoing call compared with typing it in the edit text bar (the first 
screen
you see after starting the app)

I surely don't see "send DTMF" as a menu option?  Only options for hold, mute, 
transfer, and end call?
