Extend phone line with CAT5 cable
A phone line isn't long enough to the conference cable. So I would like to extend it with a cat 5 cable.
However, there is some type of module connected to the end and the wires are colors I am not familiar with. When I take the module off I'll have five colors: Green, Brown, White, Red, Blue, and Black. It looks like the white and green are used primarily.
Which wire colors would I use on a normal cat5 cable, to connect with this legacy cable?
A picture is attached so you can see what I am working with.
At the end of the cat 5 I need it crimped to a RJ11 since it is a POTS line.

RED / GREEN is tip and ring for line 1 Yellow / Blk tip and ring for Line 2. So you can use any of the 8 wires in a CAT V cable for the 4 wires on the phone just make sure the ends match up should not need to cross any wires. Note some Telco hardware is sensitive to the tip / ring orientation but most aren't
It does not matter what colors you are using as long as it is consistent (the same wire color on both sides).

Yes, and I think you are better off to get standard telephone twisted pair made for the job. It is solid conductor and easy to strip and connect.

Based on the picture this is a standard analog phone that uses only 2 wires. The pop-up description says that you need an RJ11 on the other (unseen) end that I guess is the physical phone? If that is the case then it looks like a standard CAT3 telephone wire will do the trick with an RJ11 on both ends. You can plug an RJ11 in to a CAT5 jack
Usually an analog connection uses 2 wires but there are 4. The purpose is explained in the first comment by tmoore1962 above.
The flat ribbon cable that is in the picture is actually a 4 wire phone cable (CAT3) with an RJ45 crimped on.

If using RJ11 (2 wire standard) use RED/GREEN pair...
If using RJ14 (4 wire standard) use RED/GREEN pair in the MIDDLE connectors (LINE 1), and YELLOW/BLACK on the OUTER connectors (LINE 2).

(RJ45 is the 8 wire standard for Ethernet with Cat-5 or 6 wire)

It is typical in construction to use solid copper CAT5E for everything, including telephones.
Good practice makes sure that the cables for network and telephone are separate and, one would hope, different jacket colors.
Blue (for Red) / Blue-White (for Green) are connected to the center-most pins on an RJ-45 and the same convention can be used (and is used) for telephones going into the center-most pins on an RJ-11.
Now, I am partial to EIA 568B so the next centermost pins on an RJ-45 are Green / Green-White.
This corresponds to Green (for Yellow) and Green-White (for Black) on an RJ-11.
But gosh, the pin numbers are crazy-making if you try to keep it all straight.
RJ45
1 2 3 4 5 6 7 8
RJ11
x x 1 2 3 4 x x
RJ11 (I don't know another number for this one):
x 1 2 3 4 5 6 x
So, the primary telephone line might be wired to:
45 on RJ45
or
23 on RJ11 (4pin)
or
34 on RJ11 (6pin)
The only reason any of this might be important is if you were using a cable that's already terminated with a plug on one end. Otherwise, I'd use any twisted pair for each telephone line and keep the wires matches as expected.

Looking closer at the wiring in the biscuit jack it clearly is using the red/green pair only. The standard I have usually seen/used is the red/green pair is the center 2 pins and the black/yellow are the next pin pair out. This picture makes it look like it may be reversed.
In either case, using a standard telephone cable with RJ11 on both ends should allow the phone to function properly.

I had no idea this cable can be used for two lines. Which wires in the cable can be connected to one jack and other wires connected to another jack for two separate lines? Image showing each side of the jack.
