Hi,

If your SIP setup is working and you are happy with it then thats cool.. 
If it aint broke don't fix it..

The advantages of IAX are as you said, you can make multiple calls at 
the same time but also that NAT isn't an issue and AFAIK it doesn't have 
as much of an overhead as SIP..

Hope that helps..
