check if router support routing voice
I am not asking about what routers accept the presence of a voice card
i ask about how i can check if my router if it is routing voice and video call or not
It’s just IP packets, so any L3 device can pass through this traffic. If your question is really about routing calls in IOS, ie actually handling call routing in IOS, not “just” the IP traffic that is a different thing. You would see the presence of dial peers in your configuration if your router is setup to handle call routing. For details on how call routing in IOS is setup please have a look at this outstanding document.
What is it that you don’t understand? A router is always a layer 3 capable device.
By the way you ask questions I would recommend you to take a basic networking course or reach out to a reputable Cisco partner to seek their help on this. This community is not in a position to help you out as you clearly lack the basic understanding of networking. Sorry to be so blunt, but it is impossible to help someone who doesn’t even have basic understanding of the topic asked.
if your phones next to r1 register with CME router R2 your traffic is flowing...
If your phones are not registering with CME router R2, run debugs( depending on phone models) on R2 check if receive any registration requests..
If you want you can aslo try some wireshark capture..
