All Probably teaching you all to suck eggs but. My provider is Kingston Comms ( UK ) and I have had a bit of a struggle to get the * system setup on their cct's. Just thought I would let you all know what I had to do. Firstly order ISDN 110 they will try to provide ISDN 85 as standard. Make sure these settings are correctly defined. [zapata.conf] signalling=pri_cpe switchtype=euroisdn pridialplan=local /* And all the other stuff as usual */ If you want to send out your number i.e. SetCallerID(0870XXXXXXX) then you will need to ask for a) Type 3 agreement ( if you only have 1 number to present ) b) Type 5 agreement ( this will enable you to send out more than one number , we have a range of 0870 / 0845 .This is the one I went for ) These agreements will have to be passed through the legal dept and will be added/included with your contract, once signed the service will be activated. Datafill ( A Kingston Dept ) will need to turn the Presentation DN Service on. Not knowing what I actually needed ( newbie ) this has taken about 6 weeks to accomplish. Hopefully with these few note's it might be a bit quicker for anyone else. I must say that as a company Kingston have been more than helpful and willing to talk / guide me through this. If anyone is interested in taking a service from them email me off list and I will pass your details on to my account manager. Best Regards Simon
