Volte calling feture not working on router with airtel sim in a 5g enabled area
I have 2 tp link router tl-mr6500v . I have a airtel sim . Though internet is well working but calling feture isn't working on both router. In settings-network is 4g preferred, volte enabled in both router but still calling feture not working. I changed my preferred network to 3g but without use. I several times reset my devices. In my telephone handset dial tune is heard and telephone icon is showing in router but still no use. I used my router sim in my mobile phone and calling feture works fine. Please help.
