Have an issue affecting multiple customer and is as follows:

Receptionist answer an incoming call and transfers that call through to another extension. The extension takes the call and then places that call on hold, when they go back to retrieve the call from hold, call goes to speaker and they are unable to get the call off speaker, they must continue the conversation on speaker or hang up and call the customer back.

It is a very intermittent fault and i have been unable to replicate, although have had reports from 3 different sites. Common link seems to be a 16dli2 card.

All 3 sites are v4.93 - 2 x 7100's and 1 x 7200s

Hoping someone may have experienced the same problem.
