In the above mentioned guide, under Section 12: Caveats, it was mentioned as follows:
"I can now make outgoing phone calls on my Cisco 7960 IP phone.
However, if Voicemail in my extension configuration is set to Disabled,
and when I try to dial my DID number, it says “Number not valid”.
Only when I change Voicemail to Enabled, and when I try to dial my DID
number, it says:
“The person at extension 1600 is unavailable. Please leave your message
after the tone, when done hang up or press the # key.”
It seems that incoming calls will not be routed to extension 1600.
I will need to do more troubleshooting on this at a future date."
Now, I am pleased to announce that, this final issue has been resolved on Christmas Day 2020.
The steps taken to resolve this final issue are as follows:
Login to Teo En Ming’s FreePBX GUI at .
Click Applications > Extensions.
Click the Pencil icon to edit the PJSIP extension 1600.
Click Advanced tab.
For Rewrite Contact, you MUST change the setting from Yes to No.
Click Voicemail tab.
Change Enabled to Yes.
For Require From Same Extension, click Yes.
Click Submit.
You MUST click Apply Config for the changes to take effect!
Voila! All issues have been solved.
Thank you Stewart1!
Merry Christmas 2020!
