Cabling two router together issue

[Crunchyhippo]

I have a basic question or two about how to connect these two routers.

I have one 2600 router and another 3810 voice router. I have router-on-a-stick setup on the 2600 with two IP phones and a switch, and on the 3810 I have two analog and one IP phone (the 3810 does not support encapsulation, btw, and the 2600 has neither voice ports nor a DSP).

So at this point I'm learning how much I don't know/should know. To connect these two routers together in order to have the phones be able to talk with one another, do I use: (a)serial cable, (b)T1 crossover, or (c)regular ethernet crossover?

I only did similar labs in the classroom, where the required cables were just handed to us (my mistake - I should have figured it out myelf).

So could someone advise me on which kind of cable I should be using and why? Thanks.

That depends on how you are connecting to two routers.

A Serial connection needs a T1 cable but you need to reverse the tx and rx (pins 1245).

An ethernet would require a x-over cable....
