miniSipServer V6 is upgraded to V6.1.3. This version can support SIP INFO message to transport DTMF signals.

Some VoIP carriers’ servers or VoIP gateway can only support this INFO message to transport DTMF signals which are very necessary for IVR services, such as auto-attendant.

There are several content type in INFO message to transfer DTMF. MSS can support “application/dtmf-relay” content type.

Now, MSS can support INFO and RFC2833 for DTMF signals.
