features.conf file is where you can adjust or define the various feature parameters in Asterisk.DTMF-Based Features
Many of the parameters in features.conf only apply when invoked on calls that have been bridged by the dialplan applications Dial() or Queue(), with one or more of the options K, k, H, h, T, t, W, w, X, or x specified. Features accessed in this way are DTMF-based (meaning they can’t be accessed via SIP messaging, but only through touch-tone signals in the audio channel triggered by the users dialing the required digits on their dialpads).[97]Transfers on SIP channels (for example from a SIP telephone) can be handled using the capabilities of the phone itself, and won’t be affected by anything in the
features.conf file.In the
You also may need to take into account calls where the originating channel cannot handle a returned parked call. If, for example, the call was parked by a channel that is also a trunk to another system, there would not be enough information to send the call back to the correct person on that other system. The actions following a timeout would be more complex than
Parked calls that time out with

[general] section of features.conf, you can define options that fine-tune the behavior of the park and transfer features in Asterisk. These options are listed in Table 11.1, “features.conf [general] section”.Table 11.1. features.conf [general] section

context | <a style="color: blue; text-decoration: underline"></a>parkedcalls | Sets the default dialplan context where the parking extension and the parking lot extensions are created. |
parkinghints | <a style="color: blue; text-decoration: underline"></a>no | Enables/disables automatic creation of dialplan hints for the parking lot extensions so that phones can subscribe to the state of extensions in the parking lot. The default is no. |

comebacktoorigin | <a style="color: blue; text-decoration: underline"></a>yes | Configures the handling of timed-out parked calls. For more information on the behavior of this option, see the sidebar titled Handling Timed-Out Parked Calls with the comebacktoorigin Option. |
courtesytone | <a style="color: blue; text-decoration: underline"></a>beep | Specifies the sound file to be played to the parked caller when the parked call is retrieved from the parking lot. |
parkedplay | <a style="color: blue; text-decoration: underline"></a>caller | Indicates which side of the call to play the courtesytone to when a parked call is picked up. Valid options include callee, caller, both, or no. The default is no. |
parkedcalltransfers | <a style="color: blue; text-decoration: underline"></a>caller | Controls which side of a call has the ability to execute a DTMF-based transfer in the call that results from picking up a parked call. Valid options include callee, caller, both, or no. The default is no. |
parkedcallreparking | <a style="color: blue; text-decoration: underline"></a>caller | Controls which side of a call has the ability to execute a DTMF-based park in the call that results from picking up a parked call.[a] Valid options include callee, caller, both, or no. The default is no. |
parkedcallhangup | <a style="color: blue; text-decoration: underline"></a>caller | Controls which side of a call has the ability to execute a DTMF-based hangup in the call that results from picking up a parked call. Valid options include callee, caller, both, or no. The default is no. |
parkedcallrecording | <a style="color: blue; text-decoration: underline"></a>caller | Controls which side of a call has the ability to initiate a DTMF-based one-touch recording in the call that results from picking up a parked call. Valid options include callee, caller, both, or no. The default is no. |
parkeddynamic | <a style="color: blue; text-decoration: underline"></a>yes | Enables the dynamic creation of parking lots in the dialplan. The channel variables PARKINGDYNAMIC, PARKINGDYNCONTEXT, and PARKINGDYNPOS need to be set. |
adsipark | <a style="color: blue; text-decoration: underline"></a>yes | Passes ADSI information regarding the parked call back to the originating set. |
findslot | <a style="color: blue; text-decoration: underline"></a>next | Configures the parking slot selection behavior. See Parking Lots for more details. |
parkedmusicclass | <a style="color: blue; text-decoration: underline"></a>default | Specifies the class to be used for the music on hold played to a parked caller. A music class set in the dialplan using the CHANNEL(musicclass) dialplan function will override this setting. |
transferdigittimeout | <a style="color: blue; text-decoration: underline"></a>3 | Sets the number of seconds to wait for each digit from the caller executing a transfer. |
xfersound | <a style="color: blue; text-decoration: underline"></a>beep | Specifies the sound to be played to indicate that an attended transfer is complete. |
xferfailsound | <a style="color: blue; text-decoration: underline"></a>beeperr | Specifies the sound to be played to indicate that an attended transfer has failed to complete. |
pickupexten | <a style="color: blue; text-decoration: underline"></a>*8 | Configures the extension used for call pickup. |
pickupsound | <a style="color: blue; text-decoration: underline"></a>beep | Specifies the sound to be played to indicate a successful call pickup attempt. No sound is played by default. |
pickupfailsound | <a style="color: blue; text-decoration: underline"></a>beeperr | Specifies the sound to be played to indicate a failed call pickup attempt. No sound is played by default. |
featuredigittimeout | <a style="color: blue; text-decoration: underline"></a>1000 | Sets the number of milliseconds to wait in between digits pressed during a bridged call when matching against DTMF activated call features. |
atxfernoanswertimeout | <a style="color: blue; text-decoration: underline"></a>15 | Configures the number of seconds to wait for the target of an attended transfer to answer before considering the attempt timed out. |
atxferdropcall | <a style="color: blue; text-decoration: underline"></a>no | Configures behavior of attended transfer call handling when the transferer hangs up before the transfer is complete and the transfer fails. By default, this option is set to no and a call will be originated to attempt to connect the transferee back to the caller that initiated the transfer. If set to yes, the call will be dropped after the transfer fails. |
atxferloopdelay | <a style="color: blue; text-decoration: underline"></a>10 | Sets the number of seconds to wait in between callback retries if atxferdropcall is set to no. |
atxfercallbackretries | <a style="color: blue; text-decoration: underline"></a>2 | Sets the number of callback attempts to make if atxferdropcall is set to no. By default, this is set to 2 callback attempts. |

Handling Timed-Out Parked Calls with the comebacktoorigin Option
This option configures the behavior of call parking when the parked call times out (see the parkingtime option). comebacktoorigin can have one of two values:yes(default)- When the parked call timeout is exceeded, Asterisk will attempt to send the call back to the peer that parked this call. If the channel is no longer available to Asterisk, the caller will be disconnected.
no- This option would be used when you want to perform custom dialplan functionality on parked calls that have exceeded their timeouts. The caller will be sent into a specific area of the dialplan where logic can be applied to gracefully handle the remainder of the call (this may involve simply returning the call to a different extension, or performing a lookup of some sort).
comebacktoorigin=yes could handle gracefully.Parked calls that time out with
comebacktoorigin=no will always be sent into the parkedcallstimeout context.The extension they will be sent to will be built from the name of the channel that parked the call. For example, if a SIP peer named
0004F2040808 parked this call, the extension will be SIP_0004F2040808.If this extension does not exist, the call will be sent to the
s extension in the parkedcallstimeout context instead. Finally, if the s extension of parkedcallstimeout does not exist, the call will be sent to the s extension of the default context.Additionally, for any calls where
comebacktoorigin=no, there will be an extension of SIP_0004F2040808 created in the park-dial context. This extension will be set up to do a Dial() to SIP/0004F2040808.[98]This section allows you to define specific DTMF sequences, which will trigger various features on channels that have been bridged via options in the
Dial() or Queue() application. The options are detailed in Table 11.2, “features.conf [featuremap] section”.Table 11.2. features.conf [featuremap] section
