MIVoice Business> Conference Calling

[jabbo99]

I'm having problems with setting up conference calls with my IP phones. To start a conference call I do the following:

While initial caller (ext 101) is on the line, I press the trans/conf button
dial the number (100) of the third party
After the third party answers the call, I press the trans/conf button to conf the calls.
Instead of being connected to both parties, I am not. The display of my phone says 101 on hold. I'm connected to 100 I press the trans/conf button again but it appears to do nothing.
After disconnecting from the call, I notice that ext. 101 and 100 prime keys are active. I then noticed that those two extensions are connected.

Conference call is enabled in IP phone COS.

This is a standalone system.
I'm using Mitel 5320, 5330 and 5340 IP phones.

I believe, although I cannot find supporting documentation, that at least 1 trunk is required for conferencing

2 things to check. First, in System Options, there are 3 settings for max number of C.O Trunks, devices and Trunks allowed in a Conference. Set all three to the max of 8. A conference can consist of any combination of stations and trunks up to the max. Second, in Class of Service for the stations, check that Conference Call is set to Yes.

Thanks everyone. I changed all 3 settings in system options to 8. That resolved the issue. My oonference call option in COS for IP phones was already set to yes. Conference calls are now working.

Thank you.
