I have been recently testing the commercial EPM module ahead of rolling out a bunch of new phones to be installed in another state and country.
I have to say, its not been a smooth introduction, some useful tips would be helpful, its been 2 days of work with mixed success.
My setup comprises an (FPB14 and ASTX13). I have the commercial module and am testing with the Yealink T21PE2. The system is cloud hosted with the phone running openvpn. I am not using the redirect service offered by Yealink as yet, instead I am manually entering the provisioning server (hard provisioning) on the phone. At this point, I am using http (84) but will upgrade to https (1443) once it all works fine. The firewall is temporarily fully open both ways between the two endpoint IPs.
First of all, the phone works fine when configured manually through the phone web gui (including openvpn). The vpn config files are downloaded from the UCP and arranged as required by yealink.
When I go to test an end to end implementation, partial success. After a factory reset of the phone, the phone will semi-provision, ie. all the settings and line/account is correct but openvpn is not working. It looks like the client VPN files were not correctly loaded into the phone. If I then upload the vpn config file manually, it works fine…
Besides a rooking mistake :[ , if I was to guess the issue, the client vpn config files are not properly constructed. The symptoms are similar if you stuff this up manually…
Any suggestions or a pointer as to which specific logs might be useful?
