I have ccm 6.1 and is configured with VG via H.323. i am having two problems

i) while making conference call between internal & pstn call, none of the participants are able to hear each other's voice, well On ip phone it shows connected !!!!

internal conference between ip phones is working fine.

ii) in Call Parking, after reteriving Parked call, both of the users are not able to hear each others voice ....Call Parking between ip phones (internally) is working fine.

check IP Routing and sccp binding, make sure all voice networks and ip phones can reach proper VLan/network

Hi, try adding the "voice rtp send-recv" command on your gateway.

Hope this help
