Because the rewriting happens after Metaswitch does the toll-free lookup, the tandem rejects the call as there's no dip.<div><br></div><div>Metaswitch support had me route the call to a SIP loopback trunk, but that also fails because I don't accept transit calls. I saw the warning in the Metaswitch KB about enabling transit calls, so that doesn't excite me.</div><div><br></div><div>Are there other ways of skinning this cat, aside from rewriting to a non-toll-free number? Why I'm hesitant to do that is the goal here is to dump calls out a TDM provider instead of a SIP provider. These are priority calls and I want a backup to IP-based solutions. We don't have agreements with any TDM termination providers, so that path doesn't seem feasible either.<br><br><div><span name="x"></span><br><br>-----<br>Mike Hammett<br>Intelligent Computing Solutions<br>http://www.ics-il.com<br><br><br><br>Midwest Internet Exchange<br>http://www.midwest-ix.com<br><br><span name="x"></span><br></div><br></div></div></body></html>
