[Asterisk-Users] G729a Pass-Through and Recording/Monitoring

[Steve Totaro]

The original quesiton was that if you had a server performing G729
passthrough, could you do recording without licensing.  Digium confirmed
that the server doing the passthrough would also need a license in order
to record the conversation.  Using the Erlag formula you can pretty much
figure out how many licenses would be needed.  
 
My situation is two locations operating as a single logical call center.
G729 is good for the bandwidth and works fine with the Tenor boxes I
plan to use.  Obviously,  not all 672 channels would be in use at a time
but it could be possible and obviously not all phone calls will need to
be recorded.  Planned properly, this could amount to significant
savings.
 
Thanks,
Steve

	Only encoding and/or decoding requires a license.  If you are
just
	pushing bits you dont need a license.  This is according to
	http://www.sipro.com the people who do the licensing for G.729.
There
	is no difference in a license for decode only or encode only vs
both. 
	
	They also do G.723.1 licensing and with G.723.1 there is a
difference in
	licensing cost for decode only or encode only vs both.  So you
would see
	a savings if you were writing an app that only recorded for
example.
