VOIP

brasicot22 · ‎02-21-2008

Please help. I need to learn basic VOIP as quickly as possible. I have 2 1760 routers each with a VWIC 2MFT-T1 card and a VIC 2FXS running 12.4(18. These are connected to 2 3500 XL's with Inline Power. All I want is to be able to hook up a phone on each othe the 3500's and place a call. does anyone have a decent sample config for these?

I have never worked with voice before and it's driving me nuts. Every page I seem to find on Cisco's web sends me a different direction. If I could just see a config and find out what I need I could get it done.

Thank you - Brian

This is very basic, 12345 is an extension on RTR-B and 54321 is an extension on RTR-A.

Test with csim or pick up the phone and dial.

RTR-A#csim start 12345

RTR-A:

int eth0/0

ip add 10.1.12.1 255.255.255.0

no shut

!

dial-peer voice 1 pots

destination-pattern 12345

port 0/0

!

dial-peer voice 2 voip

destination-pattern .*

session target ipv4:10.1.12.2

!

RTR-B:

int eth0/0

ip add 10.1.12.2 255.255.255.0

no shut

!

dial-peer voice 1 pots

destination-pattern 54321

port 0/0

!

dial-peer voice 2 voip

destination-pattern .*

session target ipv4:10.1.12.1

cpubob - thank you. Maybe it's a code thing but the csim and dial-peer commands are not recognized. I am running:

c1700-ipvoice-mz.124-18.bin. Is this code good and if so is there additional SW I need to load on the router?

On your config - the ethernets are on the same subnet and so to different switches, also on the same vlan - correct? As such, no GW is needed as they never leave the subnet.

Also, I have installed many many T1 WICs, these that I am using, VWIC 2MFT T1 are not coming up. I believe the clocking needs to be set but this code does not recognize the clock source command when in the controller. Is there some sort of trick to this?

Thanks again
