Hi Everybody,
My UC System includes the following:
Cisco IP Phone 7911 do inbound and outbound call very well. But only Cisco SIP Phone 3951 can't send DTMF when meet Auto-attendants of Internal system (Unity Connection) and External System ( PSTN). I upgraded latest firmware for SIP Phone 3951 but still no lucks. Please give me some advises !
Thanks and best regards,
