Aastra Phones and TLS

[pcourtney]

we have Fusion PBX up and running with a TFTP server, we are using Letsencrypt as a wildcard cert,
but when you go into the GUI on the Aastra phones under TLS support it asks for 4 pem files, where
would we find these on the fusion pbx server please ?

 

[pcourtney]

any guidance from anyone would be very much appreciated folks

You probably won't have those files and may need to create them yourself

we went to Letsencrypt site, and found the root cert pem file which we placed on our TFTP server and typed the pem file name into the GUI on the phone - down the left hand side of the GUI is TLS Support
Root and Intermediate Certificates Filename - this is where we typed the pem file name

we can see from the TFTP logs that the Aastra 67xx phones have downloaded the pem file but get a 508 registration error in the "Phone Registration Status" on FusionPBX

there are 3 more section on the TLS Support Aastra page
Local Certificate Filename
Private Key Filename
Trusted Certificates Filename

but I have left those blank for now

it seems getting TLS working on Aastra 67xx phones is not easy DigitalDaz

has anyone ever done it ??
