I have a OS 7200-s with OAS cards. all Ip phones with sip lines. No issues with calling in and out from the phones. when we use dial block from voicemail to call outside number or cfw all from and ext to an outside number we get one way audio! Any idea?

Thank you

Have you got all the port forwards set correctly?

Remember the OS7200s has onboard MPS/RTG ports.

You need to make sure that ALL MPS/RTG ports for the onboard and the 2 x OAS cards are all different for both local and public.

I would suggest turning ON Sip>Sip mgi use in 2.1.5. I have seen this problem before and it's how I've been able to fix it. Also make sure that the VM ports are showing the correct CLI as they are initiating a conference call when using the dial block.
