Hi @anggriyulio,
Looks great – I took a skim over it and added a few minor comments in Github. If you’d like to add this plugin to the Plugin Gallery sometime, see the PKP Plugin Guide for details.
Thanks!

Thank you.
I have read your comments on github, fixed it immediately 
Hello all,
@anggriyulio, @asmecher,
Is it possible to use this with other phone communication apps?
Or each has a different api?
No, each app has a different API. This plugin only works with telegram api.
