DTMF for the star (*) key is not transmitted correctly making it difficult to use IVR and conferencing systems while calling from my RingCentral line. All the other keys work fine. I've tried dialing a landline and listening to the tones and every other key produces a normal output. The star key comes through twice. i.e., it sounds exactly like someone is pressing the star key twice in a row. This only happens with my RingCentral supplied SPA-122 ATA. My user supplied SPA-3102 ATA on a different RingCentral extension does not exhibit this behavior so it may be an issue with the ATA settings. Any ideas on how to fix?
