Compared to VoIP phones, which connect to a packet switch network, analog phones and devices connect to the public switched telephone network (PSTN). Most analog phones and devices are connected to POTS lines. Sky does not support analog phones or devices, though we do support several ATA devices to which analog devices can be connected.
Although either an analog profile or a managed profile can be used with analog phones and devices, analog profiles are recommended because of the lower monthly cost. For more information about the various types of phone profiles available in the Sky phone system, see the Phone Profile Types article.
