Incoming XOT routed to an outgoing XOT

[bsharp275153]

I currently have a serial X25 SVC to a Cisco 2800 router. This SVC is then routed to a destination server via XOT.

The x25 route statement contains two XOT destination IP addresses for redundancy.
x25 route 7000133001 xot 10.40.133.2 10.40.133.3 xot-source Loopback1

I want to replace the serial X25 SVC with an XOT connection using a software application.
The software can successfully create an XOT SVC connection directly to the destination server, but the software does not allow me to specify a redundant destination server to try if the first one is non-responsive.

So, I would like to create an XOT SVC connection to the router, then have that connection routed to another XOT SVC connection to the destination server. This will allow the router to continue to provide the redundancy I need.

It is not working. The incoming call to the router received via XOT is cleared with the following codes:
13: Not obtainable
64: Call set-up or call clearing problem.

Is it possible to configure the router to route an incoming XOT call to an outgoing XOT connection?

Hello @bsharp275153 

Yes, you can configure a Cisco router to route an incoming XOT call to an outgoing XOT connection for redundancy. Here’s how:

1. X.25 Route Configuration: Ensure the X.25 routing command is set up to handle redundancy:

   x25 route 7000133001 xot 10.40.133.2 10.40.133.3 xot-source Loopback1

2. XOT Interface Configuration: Make sure the router is configured to accept incoming XOT calls on the appropriate interface (typically using Loopback):

   interface Loopback1 ip address [Loopback IP] [Subnet Mask]

3. X.25 Switching: Enable X.25 switching on the router:

   x25 switch

If the incoming XOT call is still failing, check that the routing and interface settings match the intended configuration.
