Re: [cisco-voip] E164 routing loop

[Ki Wi]

I think I got the answer. I suppose this problem is there since day 1.

Never encounter this before as those dial-peer towards PSTN usually I will
put 9T.

In this specific gateway, it's .T .

New learning experience for me.

 Hi Group,
 I have encountered this interesting problem on customer PBX. Didn't
 work on live system for a long time but I am pretty sure this shouldn't be
 a default behavior.

 When external PSTN caller calls an unassigned number in the DID range,
 CUCM returns with error code 27 ( destination out of order).

 This causes the voice gateway to retry other dial-peers.

 There's 3 dial-peer which matches this e164 number.
 1)Dial-peer 100 goes CUCM (longest match, most specific)
 2)Dial-peer 200 goes CUCM (longest match, most specific)
 3)Dial-peer 300 goes to PSTN (the destination-pattern is .T)

 When dial-peer 100 and 200 "fails", the voice gateway will dial-out to
 PSTN via dial-peer 300. Once again, PSTN route back to the customer VG.
 This causes a routing loop and it can fills up all the available E1
 channels quickly.


 *Just wondering if anyone encounter the following issue and have a
 explanation to it? Just the engineering side of me want to get down to the
 root cause. *

 The CUCM have "stop routing on unallocated number" turns off (false).
 Just in case it matters.

 I tried to google around but can't seems to find any article that talks
 about
 1) dial-peer behaviors (on voice gateway side) - on what error code
 will cisco voice gateway retry other dial-peers?
 2) why CUCM returns error code 27?

 It's a managed service system so I'm unable to do a deep dive
 troubleshooting.

 The current workaround introduced is to create a dial-peer 250 with a
 higher preference that matches the DID range and block it.

 This means that incoming dialed number will match to 4 dial-peers (100,
 200, 250 and 300)

 After failing on 100 and 200, the call gets block on dial-peer 250.
