Hi,<br><br>I'm having difficulties with using DUNDi between two servers. If it were three I think I could control looping by limiting TTL, but with two I'm not sure how to prevent a loop causing bad things to happen. I've tried ttl=1 but things still blow up.<br>
<br>The DUNDi configurations are pretty simple and work just fine in both directions as long as only one of them is using the switch => DUNDi/context. dundi lookup <number>@dundified works great as well as test calls.<br>
<br>What is the proper method of handling DUNDi between only two servers? Should I be using a dummy context on one server to handle this?<br><br>I'm listing the relevant files below for only one server for brevities sake.<br>
