my branch office has one phone.
such phone is a Digital phone "Alcatel Lucent 4019" -- this phone is connected to a PBX that is not managed by me.
I have a ISR2019 router on my branch, my ISR2901 has 2 ports FXO card installed.
I have unplugged the RJ11 from the back of the "Alcatel Lucent 4019" and connected the RJ11 directly into the FXO of ISR2901.
I have configured the ISR as remote-site in my CUCM environment. (muti-site with centralized call agent)
my problem.
inbound calls : when I place an inbound calls from PSTN, there is no ring, and I see no activity on the ISR
outbound calls : when I place a call to PSTN, I see the FXO going up, but the called party does not ring. at the same time the call shows connected.
configuration of my FXO
voice port 0/1/0
signal loop
cptone FR
direct-inward-dial
connection plar xxxx
called-id enabled
impedance complex 2
dial-peer voice 1 pots
incoming-called-number .
port 0/1/0
my question is :
from the L1 perspective, is there any issue connecting the FXO to a PBX and get the calls from the PBX ?
from the L1 perspective, could the fact that the "Alcatel Lucent 4019" a digital phone, meaning I need a different interface than the FXO , which is analog ?

Do a quick google search on FXS vs FXO to understand each interface

what do you think I missed?, I have done the research and believe it should be working, however none of my reading are really the scenario of connecting ISR directly with PBX .
