Anthony, we need some more infromation to tell you waht's happening.

can both devices do iLBC? Trying to undesrtand what call flow is
requiing a transcoder.
Where is your transcoder physically located?

what types of devices are involved in the call?
what codecs do the devices at the central site use and what are the
model numbers of the phones in use? they don't all support iLBC.
what device pool/region is the transcoder in and what is configured
between that region and the central and remote site regions?
