PhoneA registered to CUCM (SiteA) calls PhoneD registered to CUCME (Site
C). Between Regions G729 codec is negotiated. PhoneD call-forward no
answer to Voicemail. CUE integrated with CME. After leaving the
Voicemail from PhoneA to PhoneD, when I press # key to send the
Voicemail, it is not recognized.<br>
