We are starting to provide outsourcing services for our clients where we make the outbound calls on behalf of the client. Our clients want us to use 0800, 0845 and 0870 non-geographical numbers for contact. BT have advised me that we can only have one presentation number per isdn-32 circuit. I can currently set the callerid for each of my ddi numbers, and also for any other number that is mapped / attached to our main number with no problems, but cannot set a callerid starting with 08**. Again, BY advised that I would have to install a separate isdn circuit for every 08** number that we want to present as the callerid. I find that hard to beleive - if we call out on behalf of 50 clients, I would need 50 isdn-32 circuits ?? Does anyone know of a ISDN-32 provider that want to help rather hinder a growing business ? Many thanks. Julian.
