Hi,
DTMF fails on outbound calls with CUCM 11.5 -> SIP Trunk -> CUBE -> SIP ISP. I have a CUBE that works with both inbound/outbound calls. However when I place an outbound call to an external source through the SIP ISPI can't pass DTMF. Entered digits does is not recognized.
dial-peer voice 1 voip
description OUTGOING FROM CUBE TO ISP SIP
translation-profile outgoing ISP-SIP-OUTBOUND
destination-pattern .T
session protocol sipv2
session target sip-server
voice-class codec 10
voice-class sip profiles 1
dtmf-relay sip-info
fax protocol none
I use "dtmf-relay sip-info or sip-kpml" for Out-of-band on DTMF. When I place all dial-peer to "dtmf-relay rtp-nte", DTMF works perfect on outbound calls.
Is there a command I'm missing? I need Out-of-band setup for compliance.
Thanks

Please give it a try by replacing "dtmf-relay sip-info" to "dtmf-relay rtp-nte".
Here is a document reference for this:

Does the carrier accept the out of band DTMF?
