<DIV> We have been using G711 to our branches for IPT and I am now looking at using G729. I am confused as to my transcoder requirements. I would think I would need to provision DSP based transcoder resources at the remote locations and also at the central location so G729 would always be used across the WAN. I think that transcoding resources would be required at both the remote location and the central location for the following scenarios across the WAN link:</DIV>
<DIV> </DIV>
<DIV>Calls to a centralized Unity</DIV>
<DIV>Calls to centralized PRI gateways for Long distance calling </DIV>
<DIV>Calls to/from IP phones at G711 locations?</DIV>
<DIV>Conferencing IP phones and an analog or digital trunk </DIV>
<DIV> </DIV>
<DIV>Does this look correct? For some reason determining when a transcoder is required is proving to be hard for me to grasp. Are there any other scenarios where transcoding would be required?</DIV>
<DIV> </DIV>
<DIV>Thanks!</DIV>
