So for fun (ok it wasnt really fun) I put my PIAF Asterisk service in Amazons EC2. Very cool.

I followed the guide here:

http://nerdvittles.com/?p=5060

And I had to open up various ports. 

I want to be able to access my EC2 server from home (ADSL) but also from my mobile over 3G.

Is there a better way to secure the service other than:

1. Strong password
2. Failtoban running

Cheers

Hmm a bit dodgy I suppose. I guess you could just set your security group rule to only allow traffic on 5060 from 2talk (27.111.14.65 & 27.111.14.66).
And then install a VPN server on it and connect to it that way. Probably the most secure. Otherwise you just have to rely on iptables and failtoban.

I would be really interested to hear your experience.  My first guess would be that you may have audio quality issues because of the distance to the PBX (unless your host is in Sydney).

Definitely test your fail2ban setup - perhaps using a softphone from a mobile over 3G and bad authentication details so you don;t lock yourself out accidentally from your terrestrial broadband.

What are your monthly costs going to be with this solution?

Here are the allowed IP's from 2Talk in my PBX.  Some of them may be unnecessary for your purposes.
202.180.76.164/32 Allow [2talk trunk.2talk.co.nz]
202.180.76.182/32 Allow [2talk 2talk.co.nz]
27.111.14.65/32 Allow [2talk sip.2talk.co.nz]
27.111.14.66/32 Allow [2talk peering.2talk.co.nz]

Shouldn't need those 202.x.x.x addresses as that is the old platform.

EC2 in Sydney is only around 40ms so I don't think latency should be much of an issue. I would be more concerned with the amount of cpu and ram the micro instances have. Also things like queueing and conference bridge can have varied results in virtual environments.

Just make sure fail2ban only allows a couple of attempts and bans for a looooooong time.
