Number of VoIP accounts

The largest number of VoIP accounts that can be stored in the phone.

The VoIP account determines through which server (and, accordingly, through which provider) the phone will work. Support for multiple VoIP accounts allows you to switch between them if you wish, using the one that is most convenient at the moment. For example, you can keep one number for calls within the country and use the second, with more favorable international rates, for calls abroad.
