we are using CUCM 7.0 with mobility connect feature. whenever I associate my cell phone to the IP phone as remote destination, I can't check my voicemail by cell phone. it seems when I enter my PIN, it sends wrong digit to the voicemail and it says invalid PIN. and when I remove Mobility connect, I am able to check my voicemail by cell phone. so there should be DTMF problem when cell phone is associated with IP phone as remote destination. any suggestion would be very appreciated.
