Extension call routing (need help) 1

[noidatech]

Hi experts,

We have AVAYA G3R system with 3000 users’ extension. We have another new building where we are going to deploy new telephony system (not yet decided).out of 3000 users 1000 users will move to that new building on new telephony system. We have planned for ISDN Q.SIG trunk between Avaya to new telephony system. The problem is the Avaya PBX users will move in random numbers in other building and we have to route there extensions to the new building ,we are using Uniform dial plan this way I could do the routing easily but I have limitation of AAR route patterns .

So I thought lets x –port all the moving users extensions with the VDN in cover and the calls will route using vector towards the PRI Q-SIG trunk. The main issue we are coming across is the other end telephony system will get the VDN extension as CLI not individual extensions. Can some one suggest any other way or if VDN or vector can carry the called extension number over PRI trunk to new system so that the call will directly reach to the extension on new telephony system..

I had the same issues when I moved from old building to new. I used Uniformed dial plan (UDP) with only one AAR route pattern. On cut day I removed the extension from the old switch. I then added the extension to the UDP table with a AAR code of 639 (NEW on the dial pad). The AAR code of 639 was handed to route 639. Any call (Inside or Out) was routed to the new Building. I kept my Telco trunks up at both buildings until done. Also don't forget to do the routing in reverse so that users in the new building can dial users still at the old site.

Worked Well

i do not have enough route patterns for AAR to route those calls using UDP.i am think for some other aternative so that the call can reach to another PBX with CLI information.

I find it hard to believe that you cannot spare one route for the hop over to the new building. The system limit on aar/ars route patterns are 999! One route, one AAR code one trunk group. The admin is tuff on cut night only. Once the extension is removed and placed in the UDP table your done.

I must have missed something
