The guidance was too early

From a customer, it was said that reproduction of the guidance was too early.
When I entered voicemail, it was said that I could not hear it because explanation guidance was played in succession soon.
Will there be the setting in coordination with this?
A version: Asterisk 11.6.0

Call Answer() and Wait() if you want time for the media to establish.

This is asterisk log.

I want to add a wait between each message.
For example between vm-youhave.gsm and vm-INBOX.gsm.

Hi akihiro0117.
In my case, I edited some messages to adding a pause at the end, but they were only 2.
In your case, the early playing happens with every messages?

I can’t find a setting parameter.

A voicemail guidance is too early.
(It’s not user recoding message. The message is provided the asterisk.)
Nobody is in trouble?

It’s too many message to re-recording.

Should I use AGI?
Doesn’t someone have the AGI sample of VoiceMailMain?
