I would think that the fact that the phones are connected to different
interfaces is less important to the fact that the phones are registered to
different call managers. My understanding is that the encryption used for the
phones is based upon a cert that is call manager specific and phones from
different call managers wouldn't be able to trust the cert without having the
public key made available and I do not think call manager clusters share their
keys as an enterprise PKI infrastructure would.
thoughts?

Subject: [OSL | CCIE_Security] CTIQBE application Inspection
Hi All,
Was going through the Cisco ASA 8.2 command reference for the inspect ctiqbe
command and one of the summarized point is as below
"If two Cisco IP SoftPhones are registered with different Cisco CallManagers,
which are connected to different interfaces of the adaptive security appliance,
calls between these two phones will fail"
What is the reason that the calls between those IP soft phones fail in the
above scenario.
Thanks for the help
Regards
