Mitel 112 DECT Phone - 5000 Controller

[sgates]

Hi - Our phone vendor recently set up 3 Mitel 112 DECT Phones in our 5000 controller (not sure if that makes a difference). The users are able to make and receive calls; however, when calling any phone system where there is menu that requires additional keys to be pressed on the phone, it does not seem to register that the user is pressing the keys. I am thinking it is a setting that needs to be checked but not sure where that would be. Thanks for any help

sgates,

DTMF issues usually revolve around the DTMF Decoding Payload in the MiVO-250. Do you have SIP Trunks or just this SIP DECT phone?

Thanks,

TE

I know that the DTMF Decoding Payload is set to 96 on the phone. I don't think we have SIP Trunks as we only have 5 SIP devices. We did just switch our POTS lines over to PRI lines. thanks for your assistance.

I just ran into this exact issue and found that the default DTMF Decoding payload for the Mitel 5000 is 96 and the default for the RFP 12 (112 DECT Phones) is 101. I changed the value in the Mitel from 96 to 101 and it started working for me.

P.S.  If you want to change the value on the RFP side, it is found on the "Servers" tab.
