8128 SIP Strobe Light (G2)
Setting ‘SDP SRTP Offer’ to ‘Standard’, encrypts RTP voice data, meaning the
normal audio RTP packets will now be secure (SRTP). This means SIP calls will
be rejected if other party does not support SRTP. The ‘Standard’ option secures
the audio data between parties, by making sure that it’s not left out in the open for
third parties to later reconstruct and listen to.
Important: In order for a SIP server to validate the Algo device, an additional
certificate has to be installed on the Algo device manually. For Firmware v1.7, the
only way to add this user certificate file is to use a ‘.pem’ file type extension and
have the file named ‘sipclient’. This is done by manually adding a file named
‘sipclient.pem’, which contains a device certificate and private key, to the ‘certs’
folder (under the ‘Advanced Settings’ tab File Manager’). In the future, ‘.crt’, ‘.cer’,
and ‘.der’ certificate extensions will also be supported and you will not be restricted
to naming the file ‘sipclient.pem’.
