No Voice on Teleworker using SonicWALL

[maxcheung]

I set up my TW was in connected state, if I use TW mode's phone call other phone, the phone will ringing,after i pickup the phone, both way is no voice.

is the MAS must pleace in DMZ when i use teleworker? as I watch the TW guideline.
What different between a server in DMZ and forward all port to server's ip ?
how to check MSL was in server-only mode or server-gateway mode?
my firewall is sonicwall 3060.

Thank you very much.
