[SOLVED] No matching endpoint found for inbound calls - persists after restoring from backup

Hi all,

Woke up today to a surprise issue. I’ve been getting a busy signal when calling any of our DIDs (some go to IVR, some go directly to an extension), with the following log being spit out. After reading similar stories and doing some unsuccessful troubleshooting, I decided to restore from a 9 day old backup, before we added a few new extensions the other day. Same problem. I’ve reviewed trunk settings per Flowroute, and everything is still spot on.

Hoping someone can point me in the right direction to troubleshoot this :slight_smile:

Are you able to call between extensions? Are these pjsip or sip extensions? If pjsip what do you see when you type pjsip show contacts in the asterisk console?

If sip what do you see when you do sip show peers in the CLI?

pjsip show contacts lists

I did just boot everyone off by going back to a month old backup, hence why it’s only myself and 316 connected.

Thanks for such a quick response.

Is your initial error log above from prior to the restore?

Confirm that Match (Permit) for the trunk contains
34.226.36.32/28

After the restore actually.

Flowroute just produced this log from their end, noting that they are receiving a 401:

Here’s what it’s set to currently:

I’m puzzled. I assume this is an IP auth trunk with setting Authentication None and Registration None.

At the Asterisk command prompt, type
pjsip show endpoint flowroutetrunkname
pjsip show aor flowroutetrunkname
and with luck you will see something wrong, especially look at Identify and Match.

I think I just fixed it. This is weird, hear me out:

A couple of months ago, the match (permit) field was actually set to an old IP range before a Flowroute server change. It worked fine.

I just decided to try trimming it down to only 34.226.36.32/28 in case it wasn’t parsing the whole range correctly (previously 34.226.36.32/28, 34.226.36.32-34.226.36.47). Now everything is working.

Freaking weird.
