Each time an inbound call is sent to voice mail, it records for the full 2 minutes, even if the person just leaves a 15 second message. This ties up our lines and make each message too large for convenient e-mail receipt. Can anyone identify where the setting is that would correct that? I am using a Grandstream 4108 (PSTN Lines). I am not sure if this would be a setting in the Grandstream or the 3cx console. Thanks.
