[Freeswitch-users] How the IAX2 is supported in freeswitch?

[Ken Rice]

IAX2 doesn¹t really offer that much lower bandwidth then SIP... Adjusting
the ptime on calls can achieve the same effect as enabling IAX2 trunking.
example:

G711 PCMU or PCMA at 20ms ptime is about 80kbps,

Move to G729 and this drops to 24kbps, about a 70% savings in bandwidth, now
add a 60ms ptime to this, and the bandwidth requirement drops to 13.3kbps
nearly an over all 84% savings in bandwidth...

So the who IAX argument is killed at that point
