SiP configuration for phone over VPN

[frouty (Laurent Francois)]

HI,
What should be the SIP NAT configuration option if I want a IP phone able to register over VPN ?

There is a lot of parameters :

• 1 Applications / Extensions / NAT mode : Yes (force_rport ,comedia | No | force rport | comedia | automatic force both | automatic force rport | automatic force comedia…
• 2 Settings / advanced settings / Device settings / SIP nat (à NO ce jour)
• 3 Settings / asterisk SIP setting /
  • General SIP settings tab
    • NAT settings
      • External address
      • local networks
• Chan SIP settings:
  • NAT settings
    • NAT : YES | No | Never | route

Thanks

I would expect if the phone is connecting to the local network over a VPN you would provision the phone the same as a phone on the local network.
