Flutter with FreeSWITCH

I am looking for a Flutter developer who can help me connect my app with FreeSWITCH via SIP. Specifically, I need the app to have voice calling capabilities, and it should be able to handle 6-10 concurrent calls. Simply, this will be a softphone that connects with FreeSWITCH and it is used for inbound and outbound calls control.

Skills and experience needed for this project include:

– Proficiency in Flutter development
– Knowledge of FreeSWITCH
– Experience with voice calling capabilities
– Ability to work with existing designs and implement them into the app

If you have any suggestions or ideas for the app, I am open to hearing them as well.
