I have a phone number for a conference-call service. Under ordinary use, I call the number, and when the automated system answers, I enter a 10-digit code for the conference I wish to join, and then press #. I have the number assigned to a contact like this:
When I call that contact without Google Voice enabled (either "do not use Google Voice to make any calls" or "ask every time I make a call" and then answer no), it connects fine, but when I enable GV for outgoing calls, a dialog box appears saying "Google Voice could not connect," and it gives me options of retrying with GV or to call without GV. Retrying fails in the same manner, and the latter choice allows the call to connect, but it waits for me to enter the conference code myself. It's as though GV isn't providing the conference code.
As a workaround, I can use Voice Plus; I have it set to use GV for all contacts except for those in the "No Google Voice" group, which includes the conference contact. I'd prefer not to have to do that, though, because I'd like my conference calls to show up in my GV call history, and I'd also like as few exceptions as possible to my dialing rules.
How can I get my phone to call the number through Google Voice and enter the conference code automatically?
