If you use Skype Connect and you are having DTMF (dial pad tone) issues, check the following possible causes:
| Check | Description |
| Are you using RFC 2833 (out of band) DTMF? | Ensure your SIP-enabled PBX is configured to use RFC 2833 DTMF and not in-band DTMF. We do not support in-band DTMF. |
| Are you using uncertified equipment? | Use of uncertified equipment may lead to problems with functions such as DTMF. We recommend that you use a Skype Connect certified PBX or gateway as we cannot ensure all your SIP-enabled PBX features and functions will operate correctly in non-certified SIP-enabled PBXs when used with Skype Connect.
