The reason I ask is because the customer is having an issue with it and I've never experienced a problem before so I was kinda wondering if there was a reason not to set it up this way. Data seems to be much more prevalent now a days and even commercial installs are going with VOIP systems and phones are plugged into the network wiring. I would prefer to wire everything to a patch panel and either split off using a 1x12 phone module or network switch. Commercial side can be different because of phone systems but it's much easier to carry cat5e/6 RJ45's and plate out everything using these ports.
