[asterisk-users] What is voice format 8

[Robert Moskowitz]

The IAX2 channel is to IAXmodem.
The SIP extension is an ATA with a fax attached.

IAX2/24729-2
Nov 28 15:30:20 DEBUG[2995] chan_iax2.c: Ooh, voice format changed to 8

So what does this mean?

The fax works just fine.  I am just trying to tune up my dialplan.
