VOIP Fritzbox behind Sohos XG

Hello, 

last time I got many problems with VOIP. Sometime it works great and another day it won't work.

 

Does someone get some experiances between SIP an VOIP with an Fritzbox 7490 ?

Or should I try it with an Portforwarding Rule ?

But i there a difference between a portforwarding and a "Network Rule" ?

 

Thanks 4 your help

  • Hello, 

    after testing a lot ports the follwing rule seems to work:

     

     

    And the Option NAT & Routing "Rewrite source adress Masquerading" should be disabled.

    Thanks a lot
