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.
