V21 is released today to support a new service: one number, multi-devices.
This service can enable MSS to accept several SIP phones with same local user’s number and authorization. And for incoming calls, all these phones will be ringing at the same time.
“One number” service looks like “ring group” feature. The difference is that “one number” service permits several SIP phones to share same local user profile, but “ring group” service requires SIP phones configured with different user profiles.
Please refer to following document for more details about this feature:
By the way, Cloud-MSS has been upgraded to support this feature too.
Hope you can enjoy it!
