I do agree with this side of the argument the most however it would be equally easy for a customer to put a RJ11 plug into a RJ45 jack.
I don't think either the phone or the router (or switch) would be damaged by this.
It would be easy enough to plug it into the wrong port if someone is reaching behind a desk or simply isn't paying attention.
True. I don't think "someone might do it wrong" is a reason for obliterating the mechanical differences that at least make it impossible to connect a network device to dial tone and ring tone. That makes it "it's really easy to do it wrong," which is worse.
In residential, I really like doing it as Stamp mentioned. Everything RJ45 with patch cables between the patch panel and switches or phone distribution. I was hoping to have a resounding yes or no but I see both sides.
In residential, you're more likely to have the client, who is less informed about these issues, make changes at some point and amke any mistake that can be made, so it's a good thing not to build in possible mistakes -- use RJ11 and RJ45 jacks.
Besides, just how hard is doing it right?
Also, I've run a CAT5 dedicated to phone use, and used the ancient phone installer technique of wrapping the unused wires around the jacket... then years later they need another dial tone device there, and lookie lookie -- there's two pairs of wire, ready to be used! If you punch down four pairs into an RJ45 that's used for phone, then later want to add a phone, it's a pretty clumsy thing to do.

I was in the habit of using RJ45 jacks for everything but I was finding the the RJ11 plugs didn't always seat well. There were also cases of the little gold wires in the jack being damaged - not the wires the RJ11 was actually connecting to but the outer wires being pushed on by the plastic part of the RJ11 plug.
And just how hard is doing it right?

I think you have to use 568A standard for a standard rj11 connector to work. That is if you use standard phone terminations at the block. If he is having issues and the outlet is punched using 568B, only line 1 would work. What issue is he having?
This "issue" proposes that when you do connection work at a site and one end has been punched down, you don't look to see if the previous guy used A or B. I'd say that standard practice is to see what has already been done, and either use that or repunch it to match what you want to use.

I just make custom pig tails at the room end that go from the phone to the RJ45 keystone jack. I take one of the RJ45 patch cables i have, cut an end off and put on an RJ11 connector. RJ45 plugs into the wall plate RJ11 plugs into the phone.
If I follow this correctly, you take four out of eight wires and crimp them into a connector. You can't use the strain relief properties of the connector, because there's not enough room in the connector to get the other four wires (cut short) and the jacket inside it. This is not a reliable method, especially when this splice is done at the telephone end -- the client can easily move the phone here to there while using it, stressing that non-standard connection.
How difficult is doing it right?
