my NM-HDV2 module has E1 service, it's MGCP gateways controlled by CM 4.0. Debug idsn q931 shows that external incoming calls have called number of 924003xx, and the significant digit in CM is set to 4, and I have translation pattern to translate 03xx to 13xx which is extension number range. this works all fine. But from my understanding, if i change the significant digit to other nmbers, i just need to have the right translation pattern to match it, but it doesn't work - I changed significant digit to 8 and have translation pattern as 924003xx -> 03xx, when i delete the old 03xx pattern, calls are not getting in. I have now set siginificant digti to 8 and just having 03xx translation pattern, it still works fine. I thought siginficant digit controls what is collected from gateway, so what i am doing wrong? thanks a lot.
from my experience, when you make a change such as this, ie chanign the significant digits, you need to stop and start mgcp again!
Try this and see if it works
