Andq22,
Two things to sort out – "cot" and InboundCallRoute
cot – this is just a label you make up for your User Defined DigitMap, the label could be anything. In this DigitMap you put all CallerIDs that you trust to use the single-stage bridging to your outgoing services on your OBi. This is the only security you have. You could forget it altogether, but I advise not. Set it up like so:
User Settings > User Defined Digit Maps > User Defined Digit Map2 >
Label: cot
DigitMap: (12345678)
Where 12345678 is the CallerID of your CSipSimple account. In the InboundCallRoute, where you see (Mcot) the letters Mcot will be replaced by everything in the cot DigitMap. Mcot means "cot DigitMap". Now if you add or change any CallerIDs you only have to change cot.
InboundCallRoute – As you are using sp3, all the calls you make from your CSipSimple account will be processed by the sp3 InboundCallRoute. This needs to include any routes you may wish to use. I suggest a typical one for an OBi202 might be:
Voice Services > SP3 Service > X_InboundCallRoute:
{(Mcot)>(Msp1),(Mcot)>(<**1:>(Msp1)):sp1},{(Mcot)>(<**2:>(Msp2)):sp2},{(Mcot)>(<**3:>(Msp3)):sp3},{(Mcot)>(<**4:>(Msp4)):sp4},{(Mcot)>(<**8:>(Mbt)):bt},{(Mcot)>(<**9:>(Mpp)):pp},{(Mcot)>**0:aa},{(Mcot)>0:ph,ph2},{ph,ph2}
This assumes that sp1 is your Primary Line – the one where you don't have to dial any ** codes. This rule may look slightly odd {(Mcot)>0:ph,ph2} it allows you to dial "0" from your cell phone and that will call your OBi phones at home. Very useful if you are on holiday and calling home using the hotel's free wifi
It can be useful when testing these type of setups to log into your OBi local web page and check Status > Call History. This will show you if your correct CallerID is coming in on sp3 and where the calls are being routed to.
If all of the above is set up correctly, then dialling from your cell phone should be the same as dialling from your OBi phones.
Sorry in advance for my slow responses on this forum, but I am in a different time zone.
