Wbr 1310 not updating firmware
You have 10 clients all using it at the same time and you are down to a MAX THEORETICAL bandwidth of 5mbs half duplex.
Probably closer to 3 in real life, and that isn't taking into account the impact of all those collisions is going to be having.
Quack is right, the physical ports are not a limit, but overall it's a good guideline...
I have just started using my D-Link 1310 Router after quite a few years of it laying around.
There are 2 ways to open access through your router: Use port forwarding to open only the necessary ports to the phone adapter 1) Setting your router to use the DMZ for traffic to the phone adapter: Log into your router.
If you find that your phone adapter is not able to communicate through your router, then the router is likely incompatible with Vo IP, but you can try opening the ports on the router.If you're going physical, then it is limited to your Switch ports.Some routers have settings to restrict them to less or more connections though.Most home routers are limited to a class C address which gives 254 addresses, one of which is used by the router itself, which gives 253 clients.However you are far more likely to run into limits based on either the amount of bandwidth available or the devices NAT table.
