[cisco-voip] Transcoding/Conferencing on the same ISDN Gateway

[Rhodium]

Hi Experts, :)

I am sure I read somewhere in a design doc or the SRND that it is not advocated to put transcoding or conferencing resources on a voice gateway handling about 150 calls. 

Am I recalling right or are the old brain cells getting weaker with age.

If that is correct, a link would be appreciated as I can't find it.

Regards,

Jason
