How to join Zoom meeting

[bergvdna]

Hello,
Thanks for the library for the SIM900.
But I have a question and I hope you can help me.
I want to join a meeting at Zoom (https://zoom.us/) via the SIM900.
To do this I have to enter (paste) the following (in Android phone) to automatically call:

Phone Number+Pause(2 seconds)+MeetingID+#+Pause(4 seconds)+HostID+#+Pause(4 seconds)+Password+#
(MeetingID and Password as an example)
+31207946519,,83411719839#,,,,#,,,,*999999#

gprs.callUp(PHONE_NUMBER) does not connect.
Only accepts a phone number.

Any idea how I get that to work?
Thank you very much for the effort.
Sincerely,
Arie van den Berg
