I have worked with Asterisk+DPMA for a while and i have working setup of Asterisk v15.2.0 + DPMA v15.0_3.4.5 working for awhile now without any problem.
So then i wanted to update my system.
I installed Asterisk 15.5 with DAHDI on fresh installation of CentOS 7 and all works great.
Then registered a license and installed DPMA module v15.0 successfully:
localhost*CLI> digium_phones license status OK, Valid product license found localhost*CLI> digium_phones show version Digium Phone Module for Asterisk Version 15.0_3.4.8
I have about 10 digium phones, but none of them discovers new DPMA server and none of them cannot connect to it when i configure them to connect to DPMA by IP address and port.
All of them (old Asterisk, new Asterisk and all my phones) is in the same network.
What did i missed?
How can i find any clues about what’s happening to my new system?
