We have an IPO500V2 9.0.5 with Comcast analogue lines, and a mix of 1416 and 9508 digital phones. We have been having a problem where DTMF tones stop sending in the middle of calls. Our caller reaches a vendor's auto-attendant, hits keys for options, and at some point the tones stop registering.
DTMF on the analogue lines is set for 80/80 and gain is 0/0. Some posts suggest changing DTMF to 100/80, and others suggest reducing gain to -.5.
Any suggestions?
