PRI Question

[a.gooding]

Hey,

i have a question about PRI configurations. most of my customers have T1 CAS and are now going to implement PRI. i have normally configured the main routers as H323 gatways and separated the timeslots according to customer requirements. for example

i have one customer that uses the VM AA as well as the IPCC AA on the same T1. i have two PLARS to the different pilot numbers and thats it. how do i do this with a PRI? can i split it in the same way? i also noticed that most persons configure it as an MGCP gateway. from my limited experience ive always opted to go H323 based on what i saw as instability factors (could simply be my misconfigurations but who knows).

any explanations would be greatly appreciated.

thanks in advance

Arvind,

You can have 23 calls active on a PRI, and all of them could be placed to the same number.

If you only have enough internal capacity (VM ports or wave ports) to handle 16, then the 17th call will get fast busy. Even with AA, or call center queue the calls end up getting connected to internal phones, so the bottleneck would likely be the PRI capacity.

Some phone companies will sell you a fractional PRI, usually with 12 bearer channels, rather than the standard 23.

Hi Arvind,

These are always interesting type threads, so it's good to see them pop up. Like Dave so nicely noted the PRI can route multiple calls to the appropriate areas within your Company. Your internal configuration will really determine the number of simultaineous calls to any specific number. For example;

If 800-qout routes to 644-5010 and the Phone the has 5010 on it has a "Busy Trigger" of 2 then call number 3 will get a Fast Busy.

Hope this helps!

guys i think i understand completely and here i spoke to the provider and here is what they said.

1. no multiple pilots on a single PRI becuase of only 1 D-CHANNEL

2. i can have 800 numbers and any kind of numbers in a PRI but it cannot be a pilot number (pilot meaning 800-quot is a pilot number that is also associated to say 623-4455,7623-4456 so in the even that someone calls 800-quot it routes to 623-4455 and if that is busy goes to 4456). therefore they say i can have EITHER 800-QUOT or 623-2201(which is associated with 16 pstn lines in a hunt).

3. based on this i also cannot have 800-serve and 800-care as well on the same PRI since again it is only 1 D- CHANNEL and all these are pilots that are separate trunks.

4. their recommendation is-------

so ---------------exactly hehehe...this thing is harder to understand that the ENTIRE CALL MANAGER SYSTEM..and i was soo proud when i understood CSS and partitions....lol...you know what too, its so hard to relate to these providers especially when they hold the monopoly. they rarely try to assist and the attitude is do you want it or NOT?.....its so lame

They don't seem to grasp that you want the old hunt group disconnected. All calls to 800-quot just need to go to a single number that will be routed to your PRI. There will be no overflow to any other numbers. This is not required on a PRI.

ive called a meeting with the provider. will keep you guys up to date.

again thanks for everything, these answers (not onyl the pri) help out so much when you feel youre stumped.

thanks again and i hope that one day i can return the favour.
