[asterisk-users] Best and easiest soft phone for my Dad..

[WipeOut]

Hi,

Here is the situation.. My Dad is working on contract in overseas.. He 
has internet access in his hotel.. He wants to be able to talk to my Mum 
but the calls are expensive..

I have an asterisk box setup for my business and it has a public IP 
etc.. My Mum has access to a working phone extension on this box..

I got my Dad to install X-Lite but for some reason it won't register and 
trying to talk him through working out whats wrong is proving to be 
difficult.. Also I haven't used a softphone in years.. It could be the 
NAT in the hotel, it could be a firewall or any number of things that 
can cause these issues.. It could even be X-Lite or something running on 
his PC..

So I am looking for a softphone thats really simple to setup and as 
foolproof as possible..

If SIP is likely to be problematic to setup then I have no problem 
getting him to use IAX but will need suggestions of which IAX softphone 
to use and also how to configure it in the iax.conf (haven't done this 
before)..

Any suggestions welcome and appreciated..

Thanks..
