Expressway E and C Setup - MRA
Mobile and Remote access System Configuration
Expressway MRA use for registering your remote endpoints registering with CUCM without using VPN
Few Points
* If your are deploying over WAN, minimum recommended latency is 80ms
* Remote devices will be communicating with Edge initially using the Public IP, E Usually deploy in DMZ. C takes care of LAN side communication towards CUCM
* There will be two interface for Edge. Internal and External.
* Remote devices will be registered over Core, on CUCM you could find the registered device IP as C
* If you have redundancy, Then both C act as Active - Active
---------------------DNS Records-----------------
1 - Create PTR DNS Record for each Xpressway C host
2 - Create Expressway Cluster DNS for Cluster C
3 - Create PTR DNS Record for each Xpressway E host
4 - Create Expressway Cluster DNS for Cluster E
5 - Create SRV Records
create 2 Recors for Expressway E [ port number 8443]
service : _collab-edge
Protocol: _tls
---------------------Installation MRA with Expressway-----------------

Reinstalling CUC and UCCX Subscriber
We had UCS C220, recently UCS upgraded to C240 M4SX. All the secondary UC servers were running on 220. This new UCS racked in service provider managed DC. So the IP details were different. I have re-installed the subscriber and added to existing cluster. procedure is simple, steps given below
Note - During the installation you would require to enter the Web-security details (CN,OU etc)
use 'show web-security' to get the details from CLI. you would require to enter the OS admin password as well
UCCX Installation:
- Login CCX Administration -> Go to System -> Servers -> and delete the subscriber node -> Restart the Publisher
- Once publisher is restarted check System -> Servers. Make sure Subscriber is removed from the cluster
- Start the installation, during the installation choose that this node as subscriber and enter the publisher details. Once installation completed check the cluster and DB replication. New subscriber will be part of cluster now
CUC Installation:
- Login CUC Administration -> Go to System Settings -> Cluster -> Click Find -> Choose the Subscriber node -> Delete it -> Restart the Publisher
- Once publisher is restarted, make sure Subscriber is removed from the cluster
- Start the installation, during the installation choose that this node as subscriber and enter the publisher details. Once installation completed check the cluster and DB replication. New subscriber will be part of cluster now
