Unity 4.X and CallManager 5.0 SIP Trunk DTMF

| 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.

| 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.
