    Hi olig,

     

    Since your VoIP provider has suggested it then it means that it might help for the VoIP solution to function well.  Try to follow the suggestion then observe what happens.  If ever it doesn't help then you may just delete the rules then inform your VoIP provider about it.

Hi DaneA

 

Sorry for not replying earlier, we had a long weekend due to a local holiday.

I think I'm getting closer now and I can see where to set the IP range:

However the provider is giving me 4 different IP ranges:

  • 212.55.abc.def-  212.55.uvw.xyz
  • 77.59.aaa.aaa-77.59.zzz.zzz
  • 62.2.bbb.bbb - 62.2.yyy.yyy
  • 62.12.ccc.ccc– 62.12.xxx.xxx

How can I tell which is the relevant one?

Or if all 4 are required, where do I set them?

 

Thanks and regards

Hi olig,

 

It is possible that your VoIP provider could help you determine which IP range is the relevant one.  

 

If ever all 4 IP ranges are required then I think you will need to create 4 firewall rules for each.

    Hi DaneA

     

    I have created 4 rules for inbound services and it seems to have worked. At least we are no longer getting unwanted/faked calls from strange numbers (eg.100, 1000, 1001...) which is great.

    One last question: Does it make sense to set rules for outgoing services (for VoIP) as our provider is suggesting (using the same IP ranges). What is the point in doing this?

     

    Thanks again and have a great weekend
