>> Hello.
>> I'm curious if anyone has had asterisk-ss7 working (through whatever
>> magic) across multiple boxes under a single point code.
>> For example;
>> Three asterisk boxes with 4 T1/E1 per box.
>> Box1: PC 101, CIC 1..96
>> Box2: PC 101, CIC 97..192
>> Box3: PC 101, CIC 193..288
>> I don't believe this is currently possible with a stock asterisk-ss7...
>> Any ideas on solutions to making a large quantity of trunks available
>> under a single point code?
>> (In the area of 28-500 T1s worth)
>> An a-link could be made available to each box if necessary.

Hi Mathew
How we can follow progress of your coding in more detail ?
