Is it possible to configure MessageSend in asterisk for offline users?

Question

Asterisk

There is asterisk, everything works fine. Launched MessageSend. It also works but on condition that both users are ONLINE. If the recipient is offline, he will not see the message.
Is it possible to configure in such a way that the user receives messages sent to him earlier when he appears on the network?
ps the option of delivering a message to the mail disappears due to the technical specification.

Answer 1

Check the status of the recipient, if he is online - send a message. If offline, write a message to the database. Periodically pull Asterisk with an external script via the originate file or AMI, check the status of the recipient for all messages in the database and send to those who are online.
