Thanks in advance for your assistance. I am a hobbyist/end user, not a tech guy.
I have the current FreePBX newly installed and up and running in my small office. I am trying to replace Grandstream GXP2000 phones with GXP2130 phones,
If I enable BLF on the programable keys of the GXP2130, the BLF function seems to work in that the soft keys accurately show the status of the other lines and dialing out works fine. However, incoming calls (from internal or external phones) fail and the error message says “the user at extension 101 is on the phone.”. As soon as I disable BLF, the problem disappears and incoming calls ring the phone just fine.
The “enable call waiting” option in “Advanced Settings” of the extension doesn’t seem to do anything.
Any tips will be greatly appreciated. Thanks again.
