for security reason i need to have a 'normal' fxo phone in parallel of a fxo port on a 2911.
the idea is to be able to see incoming call even in case of 2911 failure.
the 2911 is working as stand alone and not managed by call manager.
it receive fxo call and forward it in sip to another system.
the problem is
when incoming call ocuured the fxo standard phone rings only once after that the cisco 'take ' the call, in fact hook off it even if the distant still hear a ring back tone.
so my security phone is not security anymore as it only ring once
is there a setting to avoid that
i found this parameter
ring number x
documents says x is the number of rings the cisco waits to answer the call. but does it mean that the cisco will not manage at all the call and send sip invite to the second system?
my voice port is defined as this
translation-profile incoming fxo-0-0-to-sip
supervisory disconnect dualtone mid-call
non-linear threshold -30
timeouts call-disconnect 5
timeouts wait-release 5
connection plar 984
