Hi all,

I hope someone can help me with a multihome setup for Call Manager Express.

We have a 2811 as Internet-Gateway, Firewall, VPN and VoIP-System. We use SIP for external phone calls and have a SIP provider.

We got a second Internet link for failover and traffic sharing.

I have a few static routes to send all IP traffic for the SIP provider over the second ISP. The rest goes to the first ISP.

configuration snippet:

ip route <GW ISP#1> 1

ip route <GW ISP#2> 2

ip route <VoIP Net> <GW ISP#2> 1

ip route <VoIP Net> <GW ISP#1> 2

I also have two pools for NAT. I used bind (voip - sip) to bind the outbound sip traffic to the interface to ISP#2.

I'm looking for PBR, but didn't found the interface were I can configure the policy route-map for the CME.

Each ISP link has its own static IPs. No BGP possible.

Any comments are appreciated.



IOS 12.4(15)T1

CME 4.1

I have this problem too.

You can configure the policy on the interface which point to the gateway
