Group Paging
The 8138 SIP Strobe Light has been designed to support Polycom Group Paging.
The 8138 can be added to a Polycom Group Page so that voice paging is heard over
Polycom telephone speakers and visually alerted simultaneously.
TLS for SIP Signaling and Provisioning
Algo devices that support firmware 1.6.4 or later support Transport Layer Security (TLS).
This feature adds security by ensuring that Algo products can trust the hosted SIP server.
This is useful for when third-party devices or attackers may try to intercept, replicate, or
alter Algo products, and try to connect to the server. TLS protocol will ensure that third
parties cannot read/modify any actual data. Previously security was less of a concern
because phone systems were on isolated networks, but hosted services are becoming
increasingly more common. Using a hosted SIP service requires traffic to be sent over the
public internet and thus much more susceptible to attacks. Signed certificates are an
important piece in the Algo device’s operation, to ensure the security, integrity, and
privacy of its communication. Algo components that use TLS are Provisioning and SIP
Signaling.
These Algo devices each come pre-loaded with certificates from a list of trusted certificate
authorities (CA), which are installed in the hardware at the time of manufacture. Note
these pre-installed trusted certificates are not visible to users and are separate from the
‘certs’ folder.
