Meet-Me Conferencing set up

jgardner28 · December 18th, 2006, 05:49 AM

Hello,

I have been assigned the task of setting up Meet-Me conferencing. I have successfully set one up a few months back and it has been tested thoroughly. I will be setting up 100 or so in total. My question is can I point 100 vdn's to 1 vector, or do I need to dedicate 1 vdn to 1 vector?

Thank you in advance!!!

You can use the same vector as many times as you want. I would be more concerned with the Meet-Me Conferencing being overwhelmed with calls. With 100 VDNs being routed to it, there is definitely the probability that it will always be in use with conferences overlapping.

Hi Marty,

Simultaneous conferencing will be happening for sure. If this is the case then I am assuming I will need to dedicate 1 VDN per vector. Attached is a snapshot of the system capacity screen.

Thanks again!!!

To have 100 conferences up you will need 100 VDNs, that I can say for sure. The vector only references announcements. As long as the announcement is the same for all the conferences you should be able to use a single vector. To tell you the truth though, I have never tried to have that many Meet-Me Conferences programmed in one switch before.

You may have issues if you have 30 conferences all start at the same time and each with six members. The vector and the announcement board could get overwhelmed. I would keep a close eye on this for a while.

There is one step in the vector where you enter the access code, I can see a problem if 20-30 people are trying to enter a different access code at the same time. So you might need a vector for each VDN.

One vector can be linked to multiple VDNs. Be sure you have enough trunk capacity for multiple MMCB sessions. Check trunk measurements daily

Yes, one vector can be linked to multiple VDNs. But it is only one vector. If you have 30 conferences starting at the same time and each one with six members, you could have 180 people hitting this vector at the same time. If each conference has a unique access code you could have 180 people all trying to enter 30 different access codes at the same time. I have never tested a vector to see if it can do this without getting confused.

Just keep that in mind if people start complaining about a failure to get to the conference they wanted.

You don't say what kind of Avaya switch you have so this may not apply to you. Some additional call classifiers may also be needed if there is heavy traffic on the conferencing.

We are running CM 2.2 on 8710's.

I've had a lot more calls than this hitting a single vector in a scenario where different account numbers are being entered (1,000's per hour). You should be OK with regards to using 1 vector for a 100 VDN's. As stated in earlier threads, your issue will be call classifiers, time-slots or trunk capacity. Keep a close on these measurements, especially if you have time periods where a lot of conference calls are starting at the same time.

Having an S8710 answers half the question. Is the rest of the switch all IP or do you have G650's, or MCC, SCC cabinets? If you have those cabinets then call classifiers will be important to you. You will know that you do not have enough of them if people start complaining of having no dialtone or difficulty dialing.

Keep a close eye on trunking. If some of your phones are IP phones, MedPro and CLAN resources could also be an issue.

jgardner28 · December 24th, 2006, 09:49 AM

We have 3 PN's which include G650's. 90% of stations are ip, only a select few are 64xx series. We do not have any TN744 boards.

Any recommendations on listing measurements would be great!!!

I have 115 MM VDNs in service. Old school traffic analysis says about 10% of any entity in use t any one time. It would be a rare situation indeed if all 100 users tried to setup CCs at the same time. A single vector can handle all the traffic you can throw at it. Previous advise about traffic on Classifiers, PNs, etc is important anytime and critical after any major change/addition. Good luck.

Agreed with colt and martin, I wold recommend getting a feel for how frequently they will really be used. You might need to break up the vectors just for VAL resource restrictions. I forget the number of simultaneous instances a VAL can play an announcement, but you might want to spread the resources out over the highly-used with the not-expected-to-use-often bridges.

Thank you all for your suggestions!!!
