Device Compatibility
with various Telephony Systems
CallerID.com products support analog and VoIP phone service. When the phones being used can be purchased from any local retailer, then an analog Whozz Calling? unit is compatible. When VoIP phones are used, a Vertex "Caller ID for VoIP" device is required.
Analog

VoIP
Voice-over-Internet Protocol (VoIP) service is categorized as Hosted (Cloud Based) or Managed. With Hosted systems, all signaling, switching, auto attendant, and voicemail is accomplished in the cloud - you just connect the VoIP phones. Managed systems have on-premise, programmed equipment responsible for all phone related features.
Vertex units are compatible with any Hosted service using un-encrypted SIP (Session Initiation Protocol) signaling. Vertex units are compatible with most Managed VoIP systems using SIP signaling on the premise.
