Directing Voice traffic

[dathaide]

hi

I have a 64K microwave line and a 64K sat link from a remote site. If i want voice traffic traversing only the satellite connection. What is the best way to accomplish that

thanks

What you would like to accomplish can be done using Policy Based Routing (PBR).

With PBR, all packets received on an interface with PBR enabled are passed through enhanced packet filters known as route maps. The route maps used by PBR dictate the policy, determining to where the packets are forwarded.

See this good explanation for Policy-Based routing

hi

This is what i've come up with

access-list 101 permit udp any any range 16384 32767 log

access-list 101 permit tcp any any eq 1720 log

route-map voice permit 10

match ip address 101

set ip next-hop 19.6.8.21

The route map will be applied to the serial interface

My access list encompass the udp port and the tcp port that voice over ip uses. Are those sufficient?

thanks

Sounds good.

If CallManager is in the mix, see:
