Siemens Openscape Office MX - Won't allow International Dialing??

[PistonPopper]

Hi,

Hoping someone may be able to shed some light on this issue.

I am based in London,UK. We have a Siemens Openscape MX Telephony System currently running on version 3.

The problem we are having is that no matter what Siemens Openscape 40 HFA handset we use, we cannot dial international numbers, it just presents a long single beep after the first few digits have been dialed i.e. 9 for outside line preceded by 001-800-463-3768 to dial Office Depot in America as a test.

I have checked the settings in the telephony system to make sure that the users that have been set up have "unrestricted" access to dial any number and these are all set to "international" privileges within, Telephony Server>Station>IP Clients>System Clients>Extension>Edit Group/CFW and then under Class of Service these are both set to "International" (Day and Night).

Has anyone experienced this issue with this Siemens system and if so does anyone have a resolution or advice on this.

Thank you in advance,

Dominic Slaughter

Firstly you are probably not allowed to dial North America Freephone numbers from UK as the distant end would pay for the call.
You would need to dial their local code something like 001-212-XXX-XXXX rather than 001-800-XXX-XXXX

Secondly if the system was 'barring' you from making the call it would either say it or it would show up on the screen of the phone as 'unauthorised'

Hi,

I agree with sbcsu, I doubt that you are able to dial 1800 numbers directly. I know that here in NZ there is an access code you have to dial first. I would also expect an Access denied message on the phone.

sbcsu/cody64,

Firstly thank you for your responses.

We are able on another site I work at to dial the office depot freephone number from the UK and also hong kong international airport without issue, which we were using to test to see if the numbers were indeed live or actually working.

As far as I can see there are no restrictions on the handsets according to the web interface, all are set to "International" which would allow these calls to be dialled along with local numbers.

Is there somewhere else in the configuration that would set a global barring rule for all handsets regardless of what was set individually?

No access denied message appears on the phone but the user receives a "long single beep" and then the phone drops the call? I believe this is something normally received for an "Unobtainable number"?

Thanks for you help so far,

Regards,

Dominic Slaughter

Hi,
I would check with the PTT/Carrier to see if they are blocking the number, explain to them that you can dial from your other site

sbcsu,

Do you mean the line provider? If so I have already contacted them and they have confirmed that there is no barring or restrictions on the line that would be stopping international dialling.

Thanks,

Dominic

Yes but it is a North American Freephone Number that is being dialled.
Do you have any other North American (NON 800) number that you can test with to narrow down the problem?

 

[PistonPopper]

I can try another US number no problem, but It has exactly the same effect when dialling the Hong Kong International Airport.

No International numbers are working, all phones are affected and they all provide a single long beep before dropping the call once the number has been dialled.

Hi,
You could turn on the call trace for the extension you are using and see if the system selects a trunk and what it is dialling to line. Under expert, maintenance, traces, call monitoring.

One place to check may be the LCR table, maybe it is having trouble deciding what to do with the dialed number. It's in expert mode, routing if you are not familiar with it.

Check you have an entry that will catch any unspecified codes. In your case it may be something like 9CZ. There will be some default codes but we create our own to override them. Initially create a dial plan entry for the whole number you are trying to dial.

If you are using ISDN trunks check you are set to enblock sending.

Also call your provider back and get them to check again. Could there be some form of account / pin code barring on the line where the long tone is waiting for more digits to be dialled?

Cody64,

Thank you very much for your detailed breakdown, really appreciate your expertise.

We have solved it, for some reason the default 9CZ dial plan was not excepting an international number to be dialled.

A new entry was created 900CZ and now all is working!!!

Many thanks for all your help.
