Nortel MICS 4.1 Conference Call Problem with PRI

[dukeroc]

I have a customer with a Nortel MICS 4.1 wirh PRI.When a 3 party conference has been established the third party can not hear the 2nd party.I have been advised to try an upgrade to 6.1.Will this solve the problem?

upgrading to a 6.1 will not solve the problem you have with the 3rd party.

There will be drop in volume in any CO-CO conference call, but PRI is the best voice line you can get out there.

If the voice drop is unbearable conference bridge is the option to go ...if you have already done some trouble shooting with the phone company

does a 3 party conference call within the office (intercoms only) work normally?

We are experiencing the same problem with one of our customers and wondering if you were ever able to fix the problem or find a solution. Please advise at your convenience.

If by same problem you mean you also have MICS 4.1...that was buggy for many PRI 3 party operations, so the answer is to upgrade if you cant hear the third party.

But, what problem are you having? as the original post is unclear...i.e.- is it diminished volume, or that you cannot hear the third party at all?

In testing, we created a conference call between an M7310 my cell phone and my office. All three parties were in and able to hear each other until the M7310 put the call on hold and then picked the call back up. At that point the M7310 could still hear both parties but neither remote person could hear the other and the M7310 had to repeat what was being said to the other party. I am going back on site this morning to continue trouble shooting. Apparently this is how the customer has been using conferencing for some time (putting the call on hold with no music or tones) to allow the in office admin assistant to go do other things while the 2 outside talk. Any thoughts would be much appreciated.

The on-hold problem sounds like a typical 4.1 PRI bug, which calls for upgrade. But I am still not clear as to what end result you are trying to achieve. If you want to create a 3 way conference, then use conference. However, if they are actually trying to transfer an incoming call off-site to another party, use the transfer soft key, not conference and hold.

The owner calls into his personal assistant and requests that she get someone on the phone for him. She puts her boss on hold and calls the person requested, maybe having to try 2-3 numbers before she gets him on the phone. Once on the phone she then conferences her boss on and then puts them on hold without music or tones to allow them to talk while she goes on to other things. Maybe not the best way to get it done but this is how they have been doing it for a while and it not only quit working but the vendor that set it up for them stopped supporting it so I am in there trying to understand how they have been doing things and what is working and what is not.
