Am using Build v2.0.1361.0. Have set up two SIP phones and have configured them in 3CX for testing and have enabled voicemail. Calls are to be forwarded to voicemail after 15 seconds. When I call the other extension, voicemail picks up after 15 seconds and I leave a message and press # key. Then I dial 999, get the voicemail recording to enter extension number. After entering the extension number, there is a pause (I receive no prompt to enter pin number, even though it is in the 3CX setup), then the recording says "thank you, goodbye". I have not been able to get the voicemail to work properly. Is there anything else that needs to be set up to enable voicemail? Is there anything that needs to be set up in the SIP phones to enable voicemail (I'm using the Grandstream GXP-2000 and the Grandstream BT-200 phones)?
