TD-W9980 SIP filtering based on IP address

Model : TD-W9980

Hello,
I've got an VoIP phone behind my TP-Link router. It works with a SIP account that I bought from an external SIP provider. It uses 2 UDP ports to talk with the provider: 5060 and 5061.
The problem is, we receiver a lot (like, every 10 minutes) of spam calls. I'm not sure why the phone keeps ringing all the time, but it seems that the incoming requests do not come from the SIP provider's IP address.
What I would like to do is, block all the traffic on those 2 ports, except if it comes from my SIP provider's IP address (which is well known and static).
I suspect that I can use the IPv4 firewall to do that, but I couldn't make it work up to now.
Does anyone know how I can manage that?
Thanks in advance
