I have several D65 phones which are registered and making calls on Asterisk. DPMA shows the IP Address of the registered phone, but reports no MAC address. I have a few older servers still using DPMA 3.0.1 with D40 phones working fine, so I’m not sure if it’s newer DPMA or the D65 firmware. I only found one reference on the Freepbx forum which said there is a difference in the session tracking between older and newer firmware which causes this issue. Has anyone heard of this problem?
The Asterisk is hosted in a data center on a public IP.
Remote office IP is whitelisted in iptables.
Freepbx 10.13.66-17 (version 13 gui)
Digium D65 phones with 188.8.131.52 firmware
Thank you for any assistance,
