[asterisk-users] Max amount of concurrent calls on and iax trunk

[Mattias Andersson]

I agree bandwidth is the limit, however the reason to use IAX is it is
saving bandwidth.
I am runging 2 Trixbox CE with IAX over a 2 Mbit line.
I have never had any isues with the IAX trunk.
I wish that I could get son good IAX phones to the office, tan would we skip
on Trixbox and run the phones directly over a VPN Chanel. SIP over VPN are
giving more hassle then IAX sound wise.
