Strange Problem

Answered Question

Hi Netpro's


I've got a really strange problem on my hands - any help in resolving the issue would be appreciated.


Problem:


If I dial a local number (which is a DDI range on my UCM system) from my mobile lets say 8585746 as soon as the number hits my H.323 gateway an outgoing call is placed to a national number of 01xxx 515746. This number is not owened by my company. Now say I stick a phone onto extension 5746 and try and place the call again from my mobile then phone on extension 5746 rings as normal.


I have no reason to forward calls to the national number 01xxx 515746 as it's not associated to our company. We don't have any call forwarding, route lists, CTI ports, or translation patterns set up that would or could forward to this national number? it's as if my UCM database is corrup somewhere and I can't seem to figure out where? or why?


Q931 attached below to show you want I mean about a call coming into x5746 and a call being placed to national number 01xxx 515746

I doubt that the problem is on your H.323 gateway if I am reading this sentence correctly. Is it accurate to state that a) you are placing the call from a IP phone registered to UCM; and, b) you are assigning 5746 to another IP phone? If both answers are 'yes' I would focus on UCM.


There is a tool called the Dialed Number Analyzer that you can use to understand what UCM is seeing along the way. https:///dna is the URL. Run through it from perspective of the phone/DN you are making the call from. It should show you what UCM is matching.

Possibly, you have some voice translation rule in the VG that causes that.

Hi


Thanks for your reply.


Below is the config for the VG


!
voice translation-rule 2
rule 1 /^1/ /901/
rule 2 /^2/ /902/
rule 3 /^3/ /903/
rule 4 /^4/ /904/

rule 6 /^6/ /906/
rule 7 /^7/ /907/
rule 8 /^8/ /908/
rule 9 /^9/ /909/

voice translation-rule 201
rule 1 /^6/ /6/
rule 2 /^86/ /6/

Hi Thanks for your reply.


Your wrong in your assumptions. I am placing the call from my mobile phone which is not associated to UCM. If extension 5746 doesn't exisit in my UCM config as a number or route point or anything that could be attributed to a call routing funciton and I try and call the number 012925 xx5746 from my mobile the call is routed (unknown to me) to a company with no assocaition to my company on 01235 xx5746.


However I have noticed that there is a 'rouge' translation pattern that has been causing my problems within UCM. I've removed the overlapping translaiton pattern and my problem has been resolved.


Thanks to everyone of bothered to post some feedback.
