Tough luck :(. Though I am really impressed by their MSC/VLR/HLR/SMSC/GSN/AUC/EIR….(in one box), I know that its not suited for a largescale operators’ needs. Since we just want a simulated Core N/w, we are using it for our tests.
I cant contact the ADC guys on this issue, since its not critical and they will probably neglect it :)(i dont think we have a proper support contract)
I was under the impression that the usual ‘trintring’ is a GSM/ITU standard, since that sound is as old as Graham Bell himself 🙂
Anyways, let me try some other sources. By the way,Pix, I work in UK.
