[quote=“iasterix”]obviously the endpoints must have the pgp tool, but what’s the alternative?
our SME hesitates adopting * & voip just because of the security question…
skype & gizmo aren’t valuable corporate solutions so what’s left?
- the embedded iax2 RSA encryption possibility?
yes, but it’s undocumented and only works the same way (2 endpoints)
- the ranch networks HW?
yes, but it doesn’t encrypt the calls.
so, what other possibility do we have?[/quote]
Hmm. * Thinkink hard *
As for the moment it seems for me we are out of options. This will change in time when it is more common to use asterisk and voip.
But as for right now the calls go uncrypted over the network. From your (or your clients) asterisk server via IP to maybe a regular phone somewhere. If the nature of the call is somewhat buisness sensitive would you place it over IP?
For the people considering VOIP for buisness use, I belive there is only one solution at the moment, and that is to keep the regular landline for a few phones. That way it will be possible to use a “secure” line for critical phonecalls. With this approach is afew drawbacks.
1: You get to keep n* phonelines, but you need to pay for them, monthly subsription + any phonecalls made.
2: Can you as a manager be sure the employees will know when to use a secure line? They might be lazy and just place the call from wherever they sit…not relocate to make the phonecall. Which can lead to the call being recorded by unwanted parties.
3: How to organize the secure old landllines so the workers can use them when needed? How many simoultanious calls will be made? How set it up so it is easy for the enduser to make a secure call whenever needed?
Ok, one can argue and debate which call will need a secure line. But for most buisnesses I am sure they will have any number of calls they need to feel secure about, and for that they will continue to use the ol’ telecoms.
For business use it might be easier just go go with the known, rather then spending money and manhours putting up a system (asterisk pbx)that will most likely need to work in co-excistence with a regular old phonesystem.
