I have a Polycom Analog phone hooked up to a Grandstream HT287. On my GoToMeeting Bridge, I enter the number and press pount as requested. I have to press the numbers very slow and deliberate to get it to recognize all of them. I have tried an old analog house phone as well with similar results. Here are my options: I have tried all 3 options alone. -> in-audio, RTP, SIP Thank you.
