The STM-1 SIP OKEFORD now supports the receipt and transmission of out-of-band DTMF via the legacy SIP INFO method.

The SIP-INFO DTMF method includes a SIP header content type of dtmf-relay, and contains a Signal representing the tone, and a tone Duration specified in milliseconds.

SIP-INFO DTMF can be used for Grammar matching and digit collection within the OKEFORD, as well as transiting mapped digits to and from connected call legs for any supported protocol.

This enables the OKEFORD to translate and route DTMF from SIP-INFO to RFC2833, or in-band DTMF and vice-versa.
