Encryption
My setup is as follows:
Linksys SPA-3102 connecting to Voxalot, connecting to 3 different SIP providers (SipGate, Voipfone.co.uk, 3starsnet.com, used for SIP calls to european landlines, and incoming calls via my european DID numbers. I don't make SIP-SIP calls.
Can someone tell me what sort of security in terms of encryption this setup gives me, and if there are ways to improve it? I realise that it's not going to be encrypted at the PSTN-terminated end of things, but is the traffic to/from Voxalot or the SIP-providers encrypted? If it's not normally, are there ways to make it more secure?
Thanks in advance...
Ben
