Is there a cross-platform sip Softphone to work with a large number of accounts?

Good day!
Necessary Softphone to receive calls on a large number of accounts (~60).
The advantage would be the cross-platform database portability accounts(import/export or simple copypaste configs). A temporary solution for the period of configuring asterisk, I would like to know - is there such at all?
