[cisco-voip] Inbound dial-peer matching

[Norton, Mike]

I need some help understanding inbound dial-peer matching with an FXS port I'm trying to set up.

I've read the document, "Understanding Inbound and Outbound Dial Peers Matching on IOS Platforms" <http://www.cisco.com/c/en/us/support/docs/voice/call-routing-dial-plans/14074-in-dial-peer-match.html>, but the behaviour I'm seeing doesn't jive with my understanding from the document. Specifically, the document's statement that "[the incoming called-number] attribute has matching priority over the answer-address and destination-pattern commands" seems to be just plain wrong.

Config excerpt pasted below. Platform is 2911, IOS 15.3(3)M6. Port 0/2/3 is an FXS port. I want dial-peer 203 to be the outbound dial-peer for calls TO the port (works fine, no problem there), and dial-peer 6 to be the inbound dial-peer for calls FROM the port.

When I place a call from an analog set on the FXS port, the router is choosing dial-peer 203 as the inbound dial-peer. Why? The documentation says that Step 1 of inbound dial-peer matching is supposed to examine the incoming called-number command, which to me means that dial-peer 6 should win the match at Step 1. What am I missing? Dial-peer 6 does work if I shutdown 203.
