SIP Phones and use of TLS (SIP-TLS)
The use of TLS (Transport Layer Security) places additional requirements on the
MiVoice Business systems (MiVoice Business and 3300 ICP). This introduces additional limits
and considerations to the overall deployment.
The number of SIP-TLS devices that can be deployed may be different from the maximum
number of SIP devices, and is dependent on a number of factors including the number of nodes
in the cluster as well as the number of MiNet phones on the particular node.
The table below is to be used in conjunction with other standard limitation tables in these
Guidelines. The lower value of each of these is to be used. In practice, the SIP-TLS numbers
mainly impact the MiVoice Business for ISS, whereas the 3300 ICPs already have limitations
in place.
