We’re in the process of upgrading our phone system and adding some new phones. We have been running on FreePBX 2.8 or 2.9 (don’t remember) and using Cisco SPA504G phones. That setup has been working fine but we’ve had some requests for nicer phones.
Our new setup is FreePBX 2.10 and we’ve started buying Aastra 6739i phones. It took some reading to figure out to get the XML provisioning to work, but these phones are working great now with one exception: after receiving a message and then deleting it, the message light just won’t go out. As a test, we’ve plugged up one of the older Cisco phones and it works fine.
Phone: Aastra 6739i with 126.96.36.199 firmware and 188.8.131.52 boot version
