We recently upgraded to FreePBX 16.0.30 and have EndPoint Manager 16.0.71, which is fully licensed. Our Grandstream GXP2135 phones that have already been provisioned continue to work. However, when I try to provision a new phone with the Extensions module and EPM, it generates two config files in /tftpboot, one named with the MAC address, the other named cfg+MAC address. The first file is as expected, but the cfg+MAC file is truncated significantly compared to the files that were generated for the working phones before we upgraded. Here is an example of the truncated file:
▒▒▒▒t▒}<)
0=P64 = CST6CDT
&P64=CST6CDT&P72=1&P78=1&P79=101&P81=1&P91=0&P99=0&P103=1&P129=0&P130=0&P145=0&P186=0&P191=0&P192=&P193=1440&P194=2&P196=111111&P207=&P208=0&P212=0&P237=137.22.208.12:69&P271=1&P446=1&P6768=&P6769=&P2989=&P2990=&P2993=&P2994=&P20719=0&P6767=0&P2997=&P2998=&gnkey=0b82
We have largely ruled out networking and TFTP issues as everything on that front seems to be behaving as expected. The config file itself seems to be truncated or corrupted, so the phone will not apply it. This appears to be something going on with EndPoint Manager not generating the files correctly.
We tried upgrading EPM via the GUI but received the message “Enabled; Not available online”. We also tried downgrading via command line but it was not available there either. We are willing to downgrade if that fixes the issues, although we are not sure how to do so.
Any thoughts?
