Hi All,

   I got problem with dtmf RFC2833 in interconnecting with Nextone using SIP.

Nextone----------------->AS5300XM (acting as IPIP GW)------------>AS5400-------E1------->PSTN

When Nextone call in and press 103 to reach extention at my staff, my cisco AS5300XM send back OK message but when Signal-Update from SIP INFO msg my cisco AS5300XM send back Bad Request (SIP 400 msg).

Detail of debug ccsip message in my cisco as in attached file.

Thanks a lot.

did you configure dtmf-relay sip-notify or dtmf-relay rtp-nte on the AS5300 and AS5400?
