My phones are on the same local network and seems to worlk fine.
Now. I tryed to place the a phone AFTER the Nat/Router
- The phone can still register. (registration OK)
- I can make phone calls, ring any local extensions
- BUT it doesn’t ring anymore ??? ( as soon it’s outside the firewall)
Do you know, where this info is transported ? SIP protocol ?
My Firewall is opened on
SIP [5060 - 5100]
RTP [8000 - 31000]
I have the feeling that the information on “ringing” is cut by the firewall. But I don’t know what I am looking for
Thanks for your help
