Learn the essentials
Our how-to videos will teach you everything you need to know to get started with Skype.
If you use Skype Connect and you are having DTMF (dial pad tone) issues, check the following possible causes:
|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. |
