<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: SIP Options Ping Sensor

The SIP Options Ping sensor monitors the connectivity to a Session Initiation Protocol (SIP) server using SIP options "ping". The sensor sends auth and options requests to the SIP server.

i_round_blueYou can use this sensor to monitor Voice over IP (VoIP) services.

Consider the following remarks and requirements for this sensor:



.NET 4.7.2 or later

  • This sensor requires .NET 4.7.2 or later from Microsoft on the probe system. In a cluster, install it on every cluster node.

i_round_redIf the framework is missing, you cannot create this sensor.

i_square_cyanFor more information, see the Knowledge Base: Which .NET version does PRTG require?


  • This sensor supports IPv6.

Performance impact

  • This sensor has a low performance impact.


  • This sensor uses lookups to determine the status values of one or more channels.

Error message

  • An SIP server might return the error '480 Service temporarily unavailable' until at least one reachable SIP client is connected to the server.

Basic Sensor Settings

Basic Sensor Settings

Basic Sensor Settings

The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:

  • pingsensor
  • sipsensor

SIP Specific




Enter the number of the port to which this sensor connects. Enter an integer. The default User Datagram Protocol (UDP) port is 5060.

User Name

Enter the user name of the SIP user account that this sensor logs in to after a successful connection to the SIP server. Enter a string.


Enter the password of the SIP user account that this sensor logs in to after a successful connection to the SIP server. Enter a string.

Timeout (Sec.)

Enter the timeout for the connection to the SIP server. Enter an integer. The maximum timeout value is 300 seconds (5 minutes).

Retry Count

If the connection to the SIP server fails, the sensor tries to connect again. Enter the maximum number of retries. After the sensor reaches the maximum count, it shows the Down status. Enter an integer.

Result Handling

Define what PRTG does with the sensor result:

  • Discard result (default): Do not store the sensor result.
  • Store result: Store the last sensor result in the \Logs\sensors subfolder of the PRTG data directory on the probe system. The file names are Result of Sensor [ID].txt and Result of Sensor [ID].Data.txt. This setting is for debugging purposes. PRTG overwrites these files with each scanning interval.

i_podThis option is not available when the sensor runs on the hosted probe of a PRTG Hosted Monitor instance.

i_round_blueIn a cluster, PRTG stores the result in the PRTG data directory of the master node.

Primary Channel

Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel below the sensor's name. The available options depend on what channels are available for this sensor.

i_round_blueYou can set a different primary channel later by clicking b_channel_primary below a channel gauge on the sensor's Overview tab.

Graph Type

Define how this sensor shows different channels:

  • Show channels independently (default): Show a graph for each channel.
  • Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This generates a graph that visualizes the different components of your total traffic.
    i_round_redYou cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).

Stack Unit

This setting is only visible if you select Stack channels on top of each other above.

Select a unit from the list. PRTG stacks all channels with this unit on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so.

Inherited Settings

By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click b_inherited_enabled under the corresponding setting name to disable the inheritance and to display its options.

i_square_cyanFor more information, see section Inheritance of Settings.

Channel List

i_round_blueWhich channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.




In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status

Response Code

The response code

i_round_blueYou can individually define the status for each individual response code by editing the lookup file prtg.standardlookups.sip.statuscode.

i_round_blueThis channel is the primary channel by default.
