When you get the "no mgi channels" error, how many people are on the phone?

If you have 4 sip trunks and 4 mgi channels, then you can have 4 active calls going on at the same time. If you are getting no mgi channels available, this means there is either 4 active calls going whether it's people talking on the line or the calls ringing into the system.

when i get the message, only two line are being used and mo incomming calls.

When you get the error are you trying to make a call or answer a 3rd call?

i am trying to make a call on the third line

Unfortunately, the OS-7030 is not suited to the configuration that you're trying to run. When using SIP trunks with digital or analog stations, each call requires two MGI channels. With your current setup, you will never be able to have more than two simultaneous calls.

OK thats what i thought. I will have to buy more licences.

You can't get any more MGI licenses without getting a 2nd cabinet.

I have a customer with the same config as you and was having the same issue.

We checked and only 2 of the 4 mgi channels were in the MGI group. We've added the other 2 and they haven't had an issue.

Check 4.1.4 in DM and make sure there are 4 members in ALL groups.

ok thanks i'll check

Yes all 4 members are in all groups
