We have Cisco Unity 4.0 and recently when external callers leave a voicemail the voicemail does not get routed to the recipient. We get the below error in the application event log. Intenal callers voicemails do get routed to the recipient. Does anyone know why the internal voicemail gets routed and not the external ones.
to recipient <<recipient.name>> could not be delivered and was moved to the failed directory. This can occur for several reasons: the recipient mailbox may be disabled or inaccessible, Cisco Unity may be having trouble connecting with the partner server, or the Cisco Unity messaging component may not be properly configured. If this condition persists, contact Cisco TAC. 0x00001024
