International calling on SIP 1

[djgarner86]

Hello - first post here so please apologise if they have missed anything.

We have a Avaya 500v2 which we have recently migrated their lines onto SIP. All is working correctly other than international calls.

There are no shortcodes that I can see that could block this, either on the user or system wide.

I have checked with the SIP provider and the country code and / or beginning of the number is not in their blocked list.

What can I do to test this or do I need to set something up to allow international calling?

Many thanks in advance,
Daniel.

Setup a shortcode on the system of say

300
Dial
International telephone number in international format - ie 0012021234567 (US DC area code with made up 1234567 local number)
Line or ARS pointing to SIP

then ensure monitor is open and SIP trace is turned on.

From a phone dial 300 and watch what monitor shows - it will either send it to line as the full number and work, send it to line as the full number and fail, or not send it to line at all.

If the first great you know international calls work and it could just be the dialling times need amending to allow users to dial properly (international numbers are often the first to fail after a move from ISDN to SIP as on ISDN you can do add-on dialling (ie you can add digits to the number after it has started to go to line) but on SIP you have to send the whole number), so an amendment of the timers should resolve.

If the second then you can show the line provider that the number is going to line and failing.

If the third then you have an issue with the system setup.

? Which SIP provider and where are you country wise ?

Yes, there are some SIP line providers who are very loose on routing just everything. The treat a number with an without an international dialing prefix the same (eg 0044xxxxxxxx and 44xxxxxxxxxx).

Whilst that might be useful to some users, it does make it very hard to bar international calls (unless you want to bar every single country code and don't have the problem of 44 being a valid area code in Denmark).


Stuck in a never ending cycle of file copying.

Thanks for all the replies - We have managed to resolve this. The SIP provider didn't bother to let us know there was an international bar when I asked them - once I enabled international calling, all is working as it should.

Thanks again for everyone's help.
