I have configured Expressway servers. Cisco Jabber work well through Expressway. I also know that 78/8800 phone can work through Expressway, but I can't find any guide of configuration it on 78/8800 phone .
Could you provide a detail guide? thanks in advance !
Although the same MRA deployment works for both but you can also refer the following link that has details specific to 78XX seris
The latest MRA deployment guide is here

Biggest differences are that you need your EXP-E signed by a public CA whose root password is on the devices as you cannot upload new ones, and that if you need to use them with a mixed mode cluster, you need to add the device security profiles to the EXP-C certificate as SAN.
Thanks for you answer!
I don't understand that add the device security profiles to the EXP-C certificate as SAN. Could you show me more information ?
Thanks again !
The MRA configuration guide covers that part of the configuration if you're using mixed mode and want encryption end to end.
