Restricted Short Calls: Minimize FAS and Block Invalid Calls!!!

FAS is a big issue on VoIP Calls. It should be minimized to make Your Carrier Happy! Also Vendor will be happy not to get many invalid calls! You can do it from VOS3000 by ‘Callee Number Allow Length’ so some invalid numbers will not go on FAS. It can be done both on mapping gw and routing gw. It will also minimize failed calls load on your vendor setup end too.

I have allowed only 15,16 for 558801730000106,7778801730000106

But it blocked my Nepal 13 digit call 9779868091668 .. So next made allowable length 13,15,16
