I have two Cisco GWs, each has a serial interface module. I want to set them up back-to-back to send VOIP calls across the link between the routers (have set up voice using ethernet link, just need to swap to serial link now)
I have CAB-SS-X21FC (DCE) and CAB-SS-X21MT (DTE) cables connected together, then connected to Serial0/2/0 on each GW.
I am struggling to find any documentation on how to configure my GWs to enable this link between them.
Is anyone able to post example config please?
Many thanks

Just use serial interface configuration according to documentation and your study course,, and that's all.
Then on DCE side you can change clock speed to play.

Start looking at show controllers serial xxx, show interface serial xxx

I disabled frame-relay in the end and just used HDLC, which worked.
I set the clock speed on the DCE router only
