Cisco ASA Series CLI Configuration Guide
Chapter 1 Configuring the Cisco Phone Proxy
Troubleshooting the Phone Proxy
media-termination address 10.10.0.25
cipc security-mode authenticated
cluster-mode mixed
disable service-settings
timeout secure-phones 0:05:00
hostname(config)#
Make sure that each media-termination instance is created correctly and that the address or addresses are
set correctly. The ASA must meet specific criteria for media termination. See
Instance Prerequisites, page 1-6
for the complete list of prerequisites that you must follow when creating
the media termination instance and configuring the media termination addresses.
Audio Problems with IP Phones
The following audio errors can occur when the IP phones connecting through the phone proxy.
Media Failure for a Voice Call
Problem
The call signaling completes but there is one way audio or no audio.
Solution
•
Problems with one way or no audio might be caused by issues with media termination. Enter the
following command to determine if the media-termination address in the phone proxy configuration
is set correctly:
hostname(config)#
show running-config all phone-proxy
asa2(config)# show running-config all phone-proxy
!
phone-proxy mypp
media-termination address 10.10.0.25
cipc security-mode authenticated
cluster-mode mixed
disable service-settings
timeout secure-phones 0:05:00
hostname(config)#
•
Make sure that each media-termination instance is created correctly and that the address or
addresses are set correctly. The ASA must meet specific criteria for media termination. See
Termination Instance Prerequisites, page 1-6
for the complete list of prerequisites that you must
follow when creating the media termination instance and configuring the media termination
addresses.
•
If each media-termination address meets the requirements, determine whether the IP addresses are
reachable by all IP phones.
•
If each IP address is set correctly and reachable by all IP phones, check the call statistics on an IP
phone (see
Debugging Information from IP Phones, page 1-32
) and determine if there are Rcvr
packets and Sender packets on the IP phone, or if there are any Rcvr Lost or Discarded packets.
Saving SAST Keys
Site Administrator Security Token (SAST) keys on the ASA can be saved in the event a recovery is
required due to hardware failure and a replacement is required. The following steps shows how to
recover the SAST keys and use them on the new hardware.
