Under the section - Redundant Cisco unified CME router
It states the following :
"The physical setup for redundant Cisco Unified CME routers is as follows. The FXO line from the PSTN is split using a splitter. From the splitter, one line goes to the primary Cisco Unified CME router and the other goes to the secondary Cisco Unified CME router. When a call comes in on the FXO line, it is presented to both the primary and secondary Cisco Unified CME routers. The primary router is configured by default to answer the call immediately. The secondary Cisco Unified CME router is configured to answer the call after three rings using the voice-port ring number 3 command. If the primary router is operational, it answers the call immediately and changes the call state so that the secondary router does not try to answer it. If the primary router is unavailable and does not answer the call, the secondary router sees the new call coming in and answers after three rings"
My question :
Can an E1 be split like this ? or would you have to manually switchover the cable from the E1 on the primary system over to the E1 on the secondary system ?
if it can be split how do I configure the secondary router to only answer calls if the primary is down ?
Also a different question on redundancy...
Can you use a lower end spec cme router with a 24 user feature license as a backup to a bigger system with 100 users, the idea is that only certain phones (ie directors, managers) will register with the secondary router by configuring "no auto-reg-ephone" under telephony services and configuring specific ephone configurations for those phones you wish to register with the system ?
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
