We deployed about 250 Avaya 9611 phones about a year ago to various locations. However, we also have digital sets.
Last month, we started getting calls that the touch tones are not working for external calls (the strange thing is that they are working for internal auto attendants including Audix). For instance, when someone places a call to an external number from an IP phone (e.g. insurance company) and they get an auto attendant, the external auto attendants don't recognize the touch tones dialed from our IP phones. When dialing the same number from a digital set (6408D+), the touch tones work. So this appears to be isolated to IP phones, and external numbers. Any ideas?
