I've heard encrypted calls can be an issue on virtual infrastructure, I'd be interested to hear any experiences with secure sip calls if anybody has any...

It's actually for mucking around with http://sipml5.org/
Which is a HTML 5 Javascript SIP library.
There is a optional proxy server which handles transcoding where needed.

So yes transcoding is on the server, but Asterisk should be using ulaw internally for everything (i think).

Do you do any transcoding or just passing of packets ?

I've recently set up an Asterisk server on AWS just for some testing of some things but I'm generally impressed.

My setup is FreePBX/Ubuntu 14/Asterisk 12 on a t2.micro instance.

There is no appreciable lag or any issues with voice performance for 2-3 calls at once.

This isn't a final setup, just for testing and I'd probably go for guaranteed resources (not a t2) for the final setup.
It is doing the job without any struggles at all however.

Hi Noggers,

Just wanted to get some experiences from anyone who's run a VoIP/SIP soft switch on Amazon EC2.

1) Does it run ok or does it really need a dedicated machine given it's a real-time application?

2) What are you running? I'm open to the platform used commercial/free etc. I just need a solution that works really well and major bonus points for one that has an API for easy provisioning of users.
