Is it possible to perform ZoiPer call from Android/iOS app using custom url scheme without ZoiPer registration?

Question

Can you tell please if there is a possibility to perform Zoiper call from my custom Android/iOS app without registration and using custom url scheme? Can I provide all register information (account name, account type, domain, username, password) as parameters for custom url scheme link and perform call directly, avoiding registration procedure? If yes, what are custom url scheme and its parameters? Thanks.

For SIP URI dialling usually you should use the format: 
sip:user@example.com

You can enter this directly into the "search" field of Zoiper for Android or iOS and then tap on "call".

Note, you need to have at least a dummy account set in Zoiper.
