[cisco-voip] Unity 4.X and CallManager 5.0 SIP Trunk DTMF

[Ryan Ratliff]

AFAIK as long as CM gets the DTMF out of band to pass along to Unity  
everything should work.  I don't know if Unity can pick up DTMF in-band.

For Unity 4.x with UnityTSP 8.1(3) does Unity care whether my  
CallManager 5.0 SIP Trunk to telco is using dtmf-relay vs sip-kpml vs  
sip-notify?



For example with H323 Gateway I need to use dtmf-relay h245- 
alphanumeric with Unity for DTMF. There are issues with h245-signal.
