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

Question

SIP

Good afternoon!
You need a softphone to receive calls to a large number of accounts (~60).
A plus would be cross-platform and portability of the database of accounts (import / export or simple copy-paste of configs). The solution is temporary for the period of setting up the asterisk, I would like to know if there is such a thing in principle?

Answer 1

2-3 accounts, there was no more need)))
