DTMF Support on 8851 phones

[markbatts]

hi we're doing a trial of Asterisk and CUCM integration.I'm trying to find out what dtmf relay the phones support.I know they do KPML and RFC2833 , but do they do sip info or sip notify.

I've have looked through all the data sheets etc and can't seem to find the info.

Hello Mark,

88XX should do SIP Notify.

Let me check if there is a support document.

Best Regards, Jaime.
