The title of the post is : Single-Stage Dialing Through Any OBi Trunk
The description reads:
This article illustrates how to configure 1 to 98 OBi100/OBi110 devices plus any number of OBiON Apps for single-stage dialing capability. Any OBi or OBiON App can initiate a call through any trunk of any OBi. OBi's are named #2 through #99, with no OBi named #1 due to Speed Dial #1 being forced to be an OBiON App by the OBiTALK Web Portal.
I'm not sure how to describe what it does more clearly. You're wanting to do single-stage dialing through SP2 of your OBi instead of being limited to dialing through the PrimaryLine only (SP1 in your case). That's precisely what this configuration allows you to do.
It's an example showing three OBi's and their OBiTALK numbers. Given that you have only one OBi, you would only be concerned with the first OBi in the example and you'd obviously substitute your OBi's OBiTALK number for 200123002.
OBi # : OBiTALK #
==== =======
OBi #2 : 200123002
It tells you exactly what to put in various places:
Voice Services -> OBiTALK Service -> InboundCallRoute:
{(Mcot)>(Mpli):pli},{(Mcot)>(<*1:>(Msp1)):sp1},{(Mcot)>(<*2:>(Msp2)):sp2},{(Mcot)>(<*8:>(Mli)):li},
{(Mcot)>(<*9:>(Mpp)):pp},{(Mcot)>(<**1:>(Msp1)):sp1},{(Mcot)>(<**2:>(Msp2)):sp2},
{(Mcot)>(<**8:>(Mli)):li},{(Mcot)>(<**9:>(Mpp)):pp},{(Mcot):aa},{ph}
Note: Replace pli above (2 places) with the OBi's PHONE Port -> PrimaryLine trunk name (sp1,sp2,li,pp,tg1) as the OBi won't do it for you.
User Settings -> User Defined Digit Maps -> User Defined Digit MapX:
Label : cot
DigitMap : (200123002|290123456)
Note: These are trusted caller OBiTALK numbers. This DigitMap should also contain the OBiTALK numbers of any OBiON Apps that are used (290123456 represents your OBiON App OBiTALK number).
In the PHONE Port and Auto Attendant DigitMap's, change [1-9]x?*(Mpli) to [1-9]x?*@@.
In the PHONE Port and Auto Attendant OutboundCallRoute's, change {([1-9]x?*(Mpli)):pp} to {([1-9]x?*@@.):pp}
Speed Dial #2 : PP(ob200123002)
Once configured, you can dial from the OBiON App through any trunk on your OBi as follows:
18005551212 -> PrimaryLine
**1 18005551212 -> SP1 Service
**2 18005551212 -> SP2 Service
**8 18005551212 -> LINE Port
**9 200123456 -> OBiTALK Service
This configuration works equally well whether you have one OBi or 98 OBi's in a network. It supports one OBiON App or any number of OBiON Apps. I'm sorry my example illustrating the use of three OBi's made it confusing to you. I hope this helps.
