Obi202 Dial Plan / Digit Map UK configuration
kknb0800:
Hi,
I live in the UK (London) and recently bought an Obi202. I've only just started to use it but I can already see what a fantastic device it is. The main reason for buying it is to call the UK, Cyprus and Greece. I've read the admin guide and many many forum posts and I was able to put together the below configuration.
My setup is:
UK / GR / CY landline calls routed through sp1
CY mobile calls routed through sp2
GR mobile calls routed through sp3
UK mobile calls routed through sp4
(all SIP providers are in the US)
I'm probably trying to run before I can walk but what I'm attempting to do is to allow the user to dial a number as if they were in the country. I don't know if this is a good idea but from the information out there, it seemed to me as though this is possible.
The other issue I was unsure about is were it's actually best to do these number transformations? I decided upon doing the transformations in OutboundCallRoute and passing the resultant number down to the individual ITSP Profile digitmaps for validation before dialling out. This seemed the most logical way to go but I'd like to know which is best.

Service Providers > ITSP Profile C > General > DigitMap:
(003069xx.) --> GR mobile
Service Providers > ITSP Profile C > General > DigitMap:
(0447xx.) --> UK mobile
Number formats:
UK landline & mobile: 14 digits incl. country code / 11 digits if calling within the country
GR landline & mobile: 14 digits incl. country code / 10 digits if calling within the country
CY landline & mobile: 13 digits incl. country code / 8 digits if calling within the country
I would really appreciate it if someone can take a look at the above to see if what I'm doing looks correct and if it's the best way to go about implementing my desired solution. I've only been looking at this stuff for a day so I'm definitely in the learning stage and keen to ensure that I follow best practices when setting up my obi box.
Many thanks in advance!

Having read a bit more I have since made the below changes in bold:

Would this work?

kknb0800 – welcome to the forum.
The first thing to say is that there is more than one way of achieving your aims. I’ll suggest one way.
I’m assuming that your Primary Line is SP1 Service. Leave Phone Port DigitMaps and OutboundCallRoutes at default.
Service Providers > ITSP Profile A > General > DigitMap:
(<**200357>9[97]xxxxxx|<**30030>69xxxxxxxx|<0:**40044>7xxxxxxxxx|<0:0044>[12]xxxxxxxxx|0044[12]xxxxxxxxx|<:00357>[1-8]xxxxxxxS4|00357[1-8]xxxxxxx|<:0030>2xxxxxxxxx|00302xxxxxxxx)
Service Providers > ITSP Profile B > General > DigitMap:
(003579[97]xxxxxx)
Service Providers > ITSP Profile C > General > DigitMap:
(003069xxxxxxxx)
Service Providers > ITSP Profile D > General > DigitMap:
(00447xxxxxxxxx)
Try to avoid xx. where possible, it introduces delays as your OBi will wait a long time to see if you have finished dialling as it does not know how many digits to expect.
Try this solution and see if it works. I have not checked it very thoroughly, so I may have missed or added an x here or there! We may need a few posts to get it exactly right. We have not mentioned emergency numbers etc yet.
You are welcome to a full explanation of how it should work (if it does work), but not today – brain worn out now until tomorrow :)
Edit: Are you sure that all of your sip providers use the international prefix "00" - it's worth checking.

Hi ianobi,
Many thanks for replying so quickly - really appreciate you taking the time to help me.
Primary Line is indeed SP1 Service.
Just one initial question...do the maps you suggested require the user to dial **1 etc.? I can't figure out how the number would be passed to the ITSP digitmap without dialing **1 etc.
Yes, all of the providers I use require the international prefix "00" to be used.
I will give it a try and let you know how I get on :)
Many thanks again!

It should all work automagically! The OBi is very powerful at transforming and routing numbers. The Phone Port DigitMap and OutboundCallRoute work as a two-stage processor doing all the work for you. Read the first post here:
http://www.obitalk.com/forum/index.php?topic=513.msg3001#msg3001
In your setup note that ITSP Profile A = Msp1 = Mpli
Mpli is "Primary Line DigitMap". This is where digits go that are not prefaced by ** codes.
I'll work through the UK examples, as I live in the UK I should be on safe ground:
User dials 01xxxxxxxxx (UK landline). In the first stage Msp1/Mpli rule <0:0044>[12]xxxxxxxxx will replace the leading 0 with 0044 so the number becomes 00441xxxxxxxxx. In the second stage 00441xxxxxxxxx is passed to the Phone Port OutboundCallRoute. It is compared to all rules from left to right until a match is found. The only match is 0044[12]xxxxxxxxx in Msp1/Mpli. This means the number will be routed out via your Primary Line, which is sp1.
User dials 07xxxxxxxxx (UK mobile phone). In the first stage Msp1/Mpli rule <0:**40044>7xxxxxxxxx will replace the leading 0 with **40044 so the number becomes **400447xxxxxxxxx. In the second stage **400447xxxxxxxxx is passed to the Phone Port OutboundCallRoute. It is compared to all rules from left to right until a match is found. The match is found in this rule {(<**4:>(Msp4)):sp4}. The first part <**4:> removes the **4, then 00447xxxxxxxxx matches the only rule in Msp4 so the call is routed out to sp4.
Note that we have not altered the Phone Port DigitMaps or OutboundCallRoutes in any way. The OBi is designed to do a lot of the work for you. The only changes needed may be for your emergency number calls. Normally in the UK we replace 911 in the Phone Port DigitMap with 999|112. Then in the Phone Port OutboundCallRoute we create a rule such as {(999|112):sp1} which will send emergency calls out to sp1 without any reference to any other digitmaps. However, this depends upon having a local UK Voip provider to send the emergency call to.
May I ask how you are intending to receive calls? A local UK voip provider would be useful for this and for 999/112 calls. Sipgate.co.uk are good value for landline calls and provide 999/111 for free. They give you a free UK landline number. However, they are quite expensive for mobile phone calls. Maybe you could combine your Greek and Cypress mobile calls onto one voip provider to leave a space for a UK voip provider.
There's a few other issues to explain, such as Greek and Cyprus calls maybe both starting with "2"? However, this post is already long enough, so we'll leave that for another time!
