Hello Experts, we are installing some VOIP phones, and they are using dual network spliters, to avoid installing another NIC on the pc´s...

However:

PC1 has 192.168.5.200 - and the phone will have 192.168.2.10

they cannot see each other (ping) can I just re-adjust subnet mask to 255.255.248.0 ?

thanks

the best way is to setup vlans if you switch will support it. I would check with your phone vendor to see if it is supported. That way your phones will not talk to your computers and you can use just one Ethernet drop to both.
