We have a small office that is using 3cx Mini edition, version 10. All calls are handled by 3 analog phone lines and a Grandstream gateway. The 3 analog lines are in a rollover group serviced by the phone company
Incoming calls on all 3 PSTN lines are sent to a 3CX Ring Group where it rings all extensions for 15 seconds before sending the call to an extension voicemail.
Three ports for the gateway are configured in 3cx: LN10031, 32, and 33
Have been running into a situation as follows: When one call is in progress at the location, and LN10031 is in use, and a 2nd call comes in; the 2nd caller only gets ringing with no answer. The call also does not get forwarded to voicemail after 15 seconds. The 2nd call is being handled by port LN10032
The following is entered in the Server Activity Log:
Call(140): Rejected! Line is 'Busy' because number of simultaneous calls per line <callerID>@(Ln.10032@Grandstream) is limited by Administrator
There is also this in the Server Event log:
Device <callerID>@(Ln.10032@Grandstream) had no available outgoing trunk(s) for Call(140)
After this happened again this morning, I did a test where I called the location from my desk phone. While that call was in progress, I called from my cell phone. Both calls were handled ok.
It appears the 2nd call is being rejected by 3cx. Or is this something with the Grandstream gateway?
Can anyone shed any light on what is going on? I appreciate any help very much!
