vIPer Secure Cloud Phone Service
The Secure Phone Registrar and Gateway (SPRAG) is a secure cloud phone service offered by VOCAL Technologies for the Sectéra vIPer Phone and other secure phones. VOCAL’s SPRAG may be used by public, private, and governmental agencies to facilitate secure phone communications over public telephone networks. VOCAL’s SPRAG service augments the public telephone network by serving as a gateway between the V.150.1 protocol used by these secure phones and V.32/V.34 modem communications over G.711 on the public telephone network.

The Problems
Sectéra vIPer and other secure phone customers often have issues operating from their on-premises secure location with their local telephone switches and/or their organization’s designated telecom provider. The SIP-based local telephone switches and/or telecom providers typically do not understand V.150.1 and related aspects in SDP negotiations. Hence end-to-end calls are relegated to use of G.711 communications of modem signals which is often un-reliable unless the organization has a premium connection to a telephone service provider connected to the nation’s telecom backbone.
Another common problem faced by secure phone customers is operation over potentially lossy packet networks. Data modem and fax machine operations typically do not work well in most environments unless special handling is provided. In some installations, a telecom provider offers a G.711 service which usually works well for fax operations. In most installations, however, fax has to be handled by a T.38 capable Analog Telephone Adapter (ATA). VOCAL supports data (and fax) modem operations with its Analog Modem Adapter (AMA) which may be useful for some vIPer phone and other secure communications installations.
The VOCAL Cloud Server Solution
VOCAL’s SPRAG solves these problems (and others) by being located in the cloud with an MPLS connection to a major domestic telecom carrier. All of the major domestic carriers (AT&T, Verizon, CenturyLink, Level3 and Inteliquent) are well interconnected themselves. G.711 modem calls work well on these networks as VOCAL has demonstrated for years with its SAMS (SIP Analog Modem Server) and FoIP/T.38 gateways it has offered to other customers.
SPRAG works with secure phone devices as a gateway to these public telecom carriers. V.150.1 protocols are used in secure mode with the vIPer phone over the potentially lossy network connections from the secure customer to VOCAL’s SPRAG server. Once at VOCAL’s server, the G.711 modulated signals are exchanged with the other endpoint without loss (assuming the other endpoint has its own robust high-quality G.711 connection).
VOCAL’s solution is available for the Sectéra vIPer, STE/FNBDT, and other secure phones.
