Hi Sir.

Would you pls tell me What time Transcodeing and MTP function is invoked when connect VG and CCM?If the codec through all network is G711,would the Transcodeing function be used?

And if just h323 is used end2end,would MTP be used?



Other, it's no doubt the one of DSP' function ---transcoding--- is used to terminal the call form PSTN to VOIP, but how about the call from VOIP to PSTN,Would DXP be still used at this scenario?



Thanks

Hi,

"If the codec through all network is G711,would the Transcodeing function be used? "

If the VG announces G711....and the connection is to another endpoint that supports also G711...no XCODE will be necessary. XCODE normally is invoked when a codec missmatch occurs. Lets say VG announcing G729 and endpoint only support G711.
