Call2Teams - Customers
During a call you may need to use your dialpad to enter responses such as IVR menu choices. However, these do not appear to be working once the call has been established.
What To Check
Please check if you are able to support RFC2833 or the newer RFC4733 DTMF methods.
Please examine any traces you have captured to ensure DTMF is negotiated correctly throughout the entire call.
If the above steps do not reveal the issue, or you need to know what you can do to address the problem, please raise a case to us including any trace captures and the call url from the call log in the portal.
