Modification

12.2(2)XT

This command was introduced on the following platforms: Cisco 1750, Cisco 1751, Cisco 2600 series and Cisco 3600 series multiservice routers; and Cisco IAD2420 series Integrated Access Devices (IADs).

12.2(8)T

12.2(8)T1

This command was implemented on the Cisco 2600-XM and Cisco 2691 routers.

12.2(11)T

This command was implemented on the Cisco 1760 routers.

Usage Guidelines

The debug ephone alarm command shows all the SkinnyStation alarm messages sent by the Cisco IP phone. Under normal circumstances, this message is sent by the Cisco IP phone just before it registers, and the message has the severity level for the alarm set to "Informational" and contains the reason for the phone reboot or re-register. This type of message is entirely benign and does not indicate an error condition.

If the mac-address keyword is not used, the debug ephone alarm command debugs all Cisco IP phones that are registered to the router. You can remove debugging for the Cisco IP phones that you do not want to debug by using the mac-address keyword with the no form of this command.

You can enable or disable debugging on any number of Cisco IP phones. To see the Cisco IP phones that have debugging enabled, enter the show ephone command and look at the debug field in the output. When debugging is enabled for a Cisco IP phone, the debug output is displayed for the directory numbers associated with the Cisco IP phone.

Examples

The following example shows a SkinnyStation alarm message that is sent before the Cisco IP phone registers:
Router# debug ephone alarm
phone keypad reset
CM-closed-TCP
CM-bad-state

This command was introduced.

Usage Guidelines

This command displays call flow notification information for all calls between Cisco CallManager and Cisco CallManager Express, but it is most useful for filtering out specific information for transfer and forward cases. For basic call information, use the debug ephone state command.

If you do not specify the mac-address keyword, the debug ephone ccm-compatible command debugs all Cisco IP phones that are registered to the router. You can remove debugging for the Cisco IP phones that you do not want to debug by using the no form of this command with the mac-address keyword.

Debugging can be enabled or disabled on any number of Cisco IP phones. Cisco IP phones that have debugging enabled are listed in the debug field of the show ephone command output. When debugging is enabled for a Cisco IP phone, debug output is displayed for all phone extensions (virtual voice ports) associated with that phone.

Examples

The following sample output displays call flow notifications between Cisco CallManager and Cisco CallManager Express:
Router# debug ephone ccm-compatible

12.2(2)XT

This command was introduced for Cisco IOS Telephony Services (now known as Cisco CallManager Express) Version 2.0 on the Cisco 1750, Cisco 1751, Cisco 2600 series, Cisco 3600 series, and Cisco IAD2420 series.

12.2(8)T

This command was integrated into Cisco IOS Release 12.2(8)T and implemented on the Cisco 3725 and Cisco 3745.

12.2(8)T1

This command was implemented on the Cisco 2600-XM and Cisco 2691.

12.3(4)T

This command was integrated into Cisco IOS Release 12.3(4)T.

Usage Guidelines

The debug ephone loopback command sets debugging for incoming and outgoing calls on all loopback-dn pairs or on the single loopback-dn pair that is associated with the IP phone that has the MAC address specified in this command.

If you enable the debug ephone loopback command and the debug ephone pak command at the same time, the output displays packet debug output for the voice packets that are passing through the loopback-dn pair.

You can enable or disable debugging on any number of Cisco IP phones. To see the Cisco IP phones that have debugging enabled, enter the show ephone command and look at the debug field in the output. When debugging is enabled for a Cisco IP phone, the debug output is displayed for the directory numbers associated with that Cisco IP phone.

Examples

The following example contains two excerpts of output for a call that is routed through a loopback. The first excerpt is output from the show running-config command and displays the loopback configuration used for this example. The second excerpt is output from the debug ephone loopback command.
Router# show running-config

!
!
ephone-dn  42

 no huntstop
!
!
ephone-dn  43
 number 19115..
 loopback-dn 42 forward 4
!
.
.
.
A loopback call is started. An incoming call to 1911514 (ephone-dn 43) uses the loopback pair of ephone-dns to become an outgoing call to extension 1514. The number in the outgoing call has only four digits because the loopback-dn command specifies forwarding of four digits. The outgoing call uses ephone-dn 42, which is also specified in the loopback-dn command under ephone-dn 43. When the extension at 1514 rings, the following debug output is displayed:
Router# debug ephone loopback

Table 5 describes the significant fields shown in the display.

Table 5 debug ephone loopback Field Descriptions

Field

Description

Called Number

Original called number as presented to the incoming side of the loopback-dn.

Forward

Outgoing number that is expected to be dialed by the outgoing side of the loopback-dn pair.

PredictTarget Match

Extension (ephone-dn) that is anticipated by the loopback-dn to be the far-end termination for the call.

signal OFFHOOK

Indicates that the outgoing side of the loopback-dn pair is going off-hook prior to placing the outbound call leg.

Dial

Outbound side of the loopback-dn that is actually dialing the outbound call leg.

deferred alerting

Indicates that the alerting, or ringing, tone is returning to the original inbound call leg in response to the far-end ephone-dn state.

DN chain

Chain of ephone-dns that has been detected, starting from the far-end that terminates the call. Each entry in the chain indicates an ephone-dn tag and channel number. Entries appear in the following order, from left to right:

•Ephone-dn tag and channel of the far-end call terminator (in this example, ephone-dn 14 is extension 1514).

•other—Ephone-dn tag of the outgoing side of the loopback.

•lb—Ephone-dn tag of the incoming side of the loopback.

•far—Ephone-dn tag and channel of the far-end call originator, or -1 for a nonlocal number.

•final—Ephone-dn tag for the originator of the call on the incoming side of the loopback. If the originator is not a local ephone-dn, this is set to -1. This number represents the final ephone-dn tag in the chain, looking toward the originator.

codec match

Indicates that there is no codec conflict between the two calls on either side of the loopback-dn.

GetDnAddrInfo

IP address of the IP phone at the final destination extension (ephone-dn), after resolving the chain of ephone-dns involved.

disc_reason

Disconnect cause code, in decimal. These are normal CC_CAUSE code values that are also used in call control API debugging. Common cause codes include the following:

•16—Normal disconnect.

•17—User busy.

•19—No answer.

•28—Invalid number.

12.2(2)XT

This command was introduced for Cisco IOS Telephony Services (now known as Cisco CallManager Express) Version 2.0 and Cisco Survivable Remote Site Telephony (SRST) Version 2.0 on the Cisco 1750, Cisco 1751, Cisco 2600 series, Cisco 3600 series, and Cisco IAD2420 series.

12.2(8)T

This command was integrated into Cisco IOS Release 12.2(8)T and implemented on the Cisco 3725 and Cisco 3745.

12.2(8)T1

This command was implemented on the Cisco 2600-XM and Cisco 2691.

12.3(4)T

This command was integrated into Cisco IOS Release 12.3(4)T.

Usage Guidelines

Always use the no moh command before modifying or replacing the MOH file in Flash memory.

When a configuration using the multicast moh command is used and the debug ephone moh command is enabled, if you delete or modify the MOH file in the router's Flash memory, the debug output can be excessive and can flood the console. The multicast MOH configuration should be removed before using the no moh command when the debug ephone moh command is enabled.

Examples

The following sample output shows MOH activity prior to the first MOH session. Note that if you enable multicast MOH, that counts as the first session.

This command was implemented on the Cisco 1760 routers.

Usage Guidelines

The debug ephone mwi command sets message waiting indication debugging for the Cisco IOS Telephony Service router. Because the MWI protocol activity is not specific to any individual Cisco IP phone, setting the MAC address keyword qualifier for this command is not useful.

Note Unlike the other related debug ephone commands, the mac-address keyword does not help debug a particular Cisco IP phone.

Modification

12.2(15)ZJ2

This command was introduced for Cisco CallManager Express 3.0 and Cisco Survivable Remote Site Telephony (SRST) Version 3.0.

12.3(4)T

This command was integrated into Cisco IOS Release 12.3(4)T.

Usage Guidelines

Once enabled, the debug ephone qov command produces output only when the QOV statistics reported by phones exceed preset limits. Phones are polled every few seconds for QOV statistics on VoIP calls only, not on local PSTN calls. An output report is produced when limits are surpassed for either or both of the following:

•Lost packets—A report is triggered when two adjacent QOV samples show an increase of four or more lost packets between samples. The report is triggered by an increase of lost packets in a short period of time, not by the total number of lost packets.

•Jitter and latency—A report is triggered when either jitter or latency exceeds 100 milliseconds.

To receive a QOV report at the end of each call regardless of whether the QOV limits have been exceeded, enable the debug ephone alarm command in addition to the debug ephone qov command.

The debug ephone statistics command displays the raw statistics that are polled from phones and used to generate QOV reports.

Examples

The following sample output describes QOV statistics for a call on ephone 5:
Router# debug ephone qov
Mar  7 00:54:57.329:ephone-5[7]:QOV DN 14 chan 1 (1514) ref 4 called=1514 calling=8101

Table 7 describes the significant fields shown in the display.

Table 7 debug ephone qov Field Descriptions

Field

Description

Lost

Number of lost packets reported by the IP phone.

Jitter, Latency

The most recent jitter and latency parameters reported by the IP phone.

previous Lost, Jitter, Latency

Values from the previous QOV statistics report that were used as the comparison points against which the current statistics triggered generation of the current report.

Router sent pkts

Number of packets sent by the router to the IP phone. This number is the total for the entire call, even if the call is moved from one phone to another during a call, which can happen with shared lines.

current phone got

Number of packets received by the phone currently terminating the call. This number is the total for the entire call, even if the call is moved from one phone to another during a call, which can happen with shared lines.

worst jitter, worst latency

Highest value reported by the phone during the call.

Current phone sent packets

Number of packets that the current phone claims it sent during the call.

Signal Level to phone

Signal level seen in G.711 voice packet data prior to the sending of the most recent voice packet to the phone. The first number is the raw sample value, converted from G.711 to 16-bit linear format and left-justified. The number in parentheses is the value in decibels (dB), assuming that 32,767 is about +3 dB.

Note This value is meaningful only if the call uses a G.711 codec.
