The only way to do it is via a tone generator since they only strip the in-band dtmf tones. Some clients allow you to set up "in-band" unfortunately then you can't press 1 to receive calls through GC your inbound number, but you can use DTMF on call back calls.

They know about the issue and are doing nothing to fix it.
