Hi Everyone,
I have just upgraded to Fibre optic and purchased a 2860Vn-plus to replace my old 2820 Vigor, however I have run into a problem which I am not sure how to solve.

We have 3 SIP phones on the network which are preconfigured and all they need is internet connection to make and receive calls.

I have connected to new router (2860) successfully to the internet and I can make calls from the SIP Phones, however if someone rings us the phones are not ringing. I have tried everything I can thing of including disabling the ALG and SIP features of the router but nothing helps.

Does anyone know how to solve this problem?

Thanks

did you disbale the ALG and SIP on the command line?

Also try unticking Enable the First Priority for VoIP SIP/RTP: in the Quality of Service screen if you haven't done so already
