My VLAN can't reach fritzbox
I have a problem with my traffic between my voip VALN and my Fritzbox.
The problem is that if i call (with my phone) the general number (general phone number of my office) it woks but if i call from my office the sim - number shows up instead of my general office number.
The whole system of VOIP (A1) works that every phone has an own sim card and fritzbox manage or changes the numbers.
comes the problem from my rules of my voip vlan ?
Best Regards and Thank you.
