Hi!
I have problem with call plugin. When i connect to call from andriod phone - application closes.
Here is the output of my Mattermost server log

{“timestamp”:“2023-03-14 04:32:34.521 Z”,“level”:“info”,“msg”:“api endpoint requires a license”,“caller”:“web/context.go:115”,“path”:“/api/v4/users/4medqa6rjfggucm61nfgcqs17y/groups”,“request_id”:“6r61pwkokfdgzrfis861wutugo”,“ip_addr”:“127.0.0.1”,“user_id”:“4medqa6rjfggucm61nfgcqs17y”,“method”:“GET”,“err_where”:“”,“http_code”:501,“error”}

From browsers (pc, android), pc app calls works correctly.
Mattermost version 7.7.2
Calls plugin version 0.14.0
Please, help me to solve this problem

I think the problem is with the Mattermost call plugin.

the “failed to read RTP packet” error suggests that there may be a problem with the plugin’s ability to process voice data.
a “callback failed: not found” error may indicate that the plugin is having problems communicating with the Mattermost server or with other components of the plugin system.

Try to check the update and make sure the server and the phone are using the same version of the calling plugin
