Simultaneous call limitation
It is possible to limit simultaneous calls per provider/DID/user/device basis.
These settings limit simultaneous calls, not how many total calls the user/device/provider(/did) can make.
When no more calls can be made, the dialer hears the BUSY signal.
Hangupcause code 223 means that the provider can't make more simultaneous calls.
This limit is for outgoing calls through this provider.
Hangupcause code 220 means that the user can't make more simultaneous calls.
Hangupcause code 222 means that a reseller (as a user) can't handle (allow to his users to make) more simultaneous calls.
This limit is for outgoing calls made by this user.
Hangupcause code 221 means that the device can't make more simultaneous calls.
This limit is for outgoing calls made by this device.
NOTE: MOR uses internal call limiting engine, so call limit which is shown in "sip show peer" output, has no relation to the Call Limit in the MOR GUI.
Hangupcause code 219 means that DID can't receive more simultaneous calls.
This limit is for incoming calls made to this DID.
When DID points to a device and the limit is reached, calls will be routed to the device via BUSY - Call Flow. This will ring another device or send a call to VoiceMail when the main device already has a call.
