SIP trunk to ISP with CUBE (H323 to SIP)Inbound/outbound call is fine. Inbound DTMF works. Outbound DTMF work intermittently with random digit drop. (happens to approx 1 out of 3 calls) "debug voip rtp session named-event" shows router sending the correct digit out to telco everytime. What could be causing this?
dial-peer to UC: dtmf-relay h245-alphanumeric
dial-peer to telco: dtmf-relay rtp-nte digit-drop
MTP: use IOS MTP on the same router
