Nope, only one 911RP needed. You will need to ensure that your outbound
route is good, meaning CER can successfully redirect the call to the
correct 911 service. This will be sending the call out the correct local
GW. I would turn up detailed CER tracing & see what in going on inside
CER.

Do I need to set up JTAPI CTI route points on each cluster for CER and
send 911 calls from the remote clusters to them, or is it acceptable to
route 911 over an intercluster trunk to CTI route points built on a
single central CM cluster.  I'm having issues with phones calling out
with the default ERL ELIN using the latter method, even though CER sees
the phone on the remote cluster and the switchport it's connected to has
been assigned an ERL.  Any guidance would be appreciated.  Thanks in
advance!
