[Asterisk-Users] Re: Strategy for a stable IAXy

[Anton Krall]

How do you make SIP work behind NAT without having to change anything on the
firewall for example, those cable modems....

So far, Ive tested this using softphones and only iaxphone has been able to
work using IAX, eye lite or something for FWD that uses SIP says it cant
connect to the provider... 

So, which way to go? IAX or SIP? IAXy or Sipura?

All ip phones use SIP right?

There is no low bandwidth codec available with the IAXy that I know of... 
Minimum is 32k + IP overhead

SIP does work through NAT btw..
