We have implemented a remote VG site with CUE at Local Office. This VG is connected to CUCM 7.0.2 at our Head Office over the WAN .
· In local local Office we have configured G.711 compression (as CUE can only use G.711)
· The WAN uses G.729 compression (the our local router is doing the conversion)
· IP phones at the Head Office are using G.729 compression
Users in local can hear the CUE AA prompts OK, but the users who dial the AA from IP phones in Head Office cannot hear the AA prompts at all. They cannot even hear the music-on-hold. I suspect that this is happening due to Codec diffrence.
Question: Can this issue be resolved by specific configurations in CUCM?
