Problem with incoming calls from external source

[andrewscheng]

Hello everybody, we are currently having problems with incoming calls on our 3CX. We have a Grandstream GXW4104. We have also configured an extension # of 124 (registered to a GS GXP2020 feature phone). Also, port #1 of the Grandstream GXW4104 is connected to a PSTN line and is registered to the 3CX with a virtual extension # of 10009. Calls to port #1 (virtual extension 10009) are set to "CONNECT TO EXTENSION" # 124 under the PSTN DEVICES > EDIT GATEWAY > EDIT PORT SETTINGS. Here's the problem, if local 124 is currently talking to another local (extension) #, external callers passing through the VoIP gateway on port #1 (virtual extension 10009) that are supposed to be forwarded to extension # 124 still has ringing signal instead of a busy signal. Is there any way for the external caller to hear a busy signal instead of just ringing?
Because callers might think that their calls are not being attended to.

Thanks in advance.

Is ext 124 set to allow call waiting?

Under extensions - forwarding rules - what is busy detection setting set to?

"Use PBX status" will make the line busy if a call is on it and you can then forward to voice mail.

If you want more than 1 call to your phone use - "Use Phone Status"

@leejor : You mean the PSTN line on the GXW4108 itself? No call waiting for the PSTN line.

It is set to "Use PBX status". Anyway, we have a crude work around for this. We just created a digital receptionist and while the extension is busy, calls are forwarded (under FORWARDING RULES) to a digital receptionist that will notify the caller that the extension is currently busy.

Any suggestions are still welcome.

Thanks almiller1963.
