Incoming calls

On this tab, you can configure incoming call processing for accounts with this product and define the default values of the service attributes.

By default, the administrator can enable/disable service features for accounts that use this main product. To let end users enable/disable service features on their self-care interface, select the End users checkbox.

Auto attendant is an automated voice service in which callers are automatically transferred to an extension without the interference of an operator. When enabled for an account, PortaSIP routes all incoming calls to the auto attendant, even if the Unified messaging service is also enabled.

Turn on the toggle to activate auto attendant.

Call screening allows users to treat their incoming calls according to predefined rules, e.g., to redirect all calls to the voicemail during non-working hours, yet allow calls from your boss to always come through.

Turn on the toggle to activate call screening.

Call waiting alerts users of one or more calls awaiting connection during a current conversation. Users can answer the second call while the first one is put on hold.

Turn on the toggle to enable this feature.

Enable this feature to configure the incoming call verification in PortaBilling. Verification works only if the incoming INVITE request contains an Identity header.

Select where PortaSIP adds the verification result:

• Caller name and SIP headers – PortaSIP adds the result to the SIP headers and to the caller name. The callee’s phone shows [V] before the number of a verified caller.
• SIP headers only – PortaSIP adds the result to the SIP headers only. The caller name doesn’t change. Use this option if the callee’s phone or PBX reads the result from the headers and shows its own indicator.

Allow end users to see the caller information for incoming calls.

Turn on the toggle to enable this feature.

This allows users to see the actual name of the caller retrieved from the CNAM database, in addition to the phone number. You must be integrated with the CNAM provider and configure the CNAM lookup on the Configuration server. Then, during incoming calls, PortaSIP sends CNAM requests and retrieves the caller ID. Currently, PortaSwitch is integrated with OpenCNAM, which supports numbers from the USA and Canada.

Turn on the toggle switch to enable this feature.

If you operate as an MVNO with PortaSIP integrated in the IMS core as a telephone application server, you can redirect your users’ incoming calls to the voicemail service of your host MNO. When a user doesn’t answer an incoming call, PortaSIP sends the call to the IMS with the information to forward it to the voicemail. The IMS terminates the call and launches the voicemail application.

To redirect user calls to the external voicemail service, you must include the Out HDR history and Append incoming headers attributes in the service policy for the outgoing vendor connection that represents the IMS.

Specify the access number of the external voicemail service. Users will dial it to manage their voice mailbox.

Allow users to forward their incoming calls according to the defined forwarding mode.

Turn on the toggle switch to enable this feature.

To let end users manage how their incoming calls are processed, make sure the Can be edited by option is enabled for end users. End users can then change these settings through an IVR and their self-care interface.

This defines how to process incoming calls. Select one of the forwarding modes:

• Follow-me – lets users set multiple call forwarding destinations, each active during its own time period. Users can also choose whether these numbers ring one after another, all at the same time, or by percentage, with incoming calls split among the numbers.
• Advanced forwarding – provides extra options for the follow-me mode. Users can select the SIP proxy to which PortaSIP will route their calls.
• Forward to SIP URI – lets end users enter a forwarding destination as a SIP URI in the format CLD@IP or CLD@domain. If the domain has DNS SRV records, PortaSIP goes through them in round-robin order. Use this mode to forward calls to an external SIP proxy.
• Simple forwarding – forwards all calls unconditionally to a single phone number, pre-defined by the user.

Specify how many forwarding destinations are concurrently active at any given moment. This doesn’t limit the total number of phone numbers entered by the user in the forwarding list. For instance, a user may have a list of 20 numbers, each active in its own time period, some temporarily turned off, etc. When call forwarding is done, PortaBilling computes a list of numbers which may be used at that moment, and chooses only the first N in the list, where N is the number specified in Maximum forwards.

This option is active only when call forwarding is enabled.

This allows users to transfer incoming calls forwarded to their mobile phones from their PBX extensions by dialing DTMF tones on their mobile phone. Users stay on the line until the other party picks up.

For example, if a user receives a call to his mobile phone and needs to transfer it to his colleague at extension 1002, he dials *661002#, and when his colleague confirms that she is free to take the call, he hangs up.

This option is active only after you select one of the forwarding modes.

You can replace ordinary ringback sounds with custom tones (e.g., music). Turn on the toggle to activate custom ringback tones. To allow users to upload their own music files or greetings, enable the Can be edited by end users checkbox.

Upload the file with custom ringback tones that callers will hear instead of ordinary sounds.

By default, SIP registration is enabled for a product, which means that IP phone (SIP user agent) registration is allowed for all accounts that use this product. When an incoming call arrives, the IP phone registered with the account’s credentials rings.

If incoming calls should not ring on an IP phone, you can prevent IP phone registration for such accounts by disabling this option for a product or a specific account.

For example, since the calls to Auto Attendant should be routed to the IVR and are answered automatically, no IP phone must be registered with an account configured as Auto Attendant. If an IP phone is registered with such an account by mistake, the calls will be routed to the IP phone. To avoid this, the administrator can explicitly forbid IP phone registration with Auto Attendant.

Turn off the SIP registration toggle for a product with the enabled Auto Attendant to prevent IP phone registration.

Allow access to the unified messaging system for accounts with this product.

Turn on the toggle to allow end users to access their voice mailbox and/or redirect incoming calls to the voicemail.

Specify the maximum disk space for each user mailbox. This helps you control how much disk space the voicemail system uses overall.

To enable automated voicemail transcription for users, turn on the toggle and select the speech-to-text service from the drop-down list.

This feature allows your customers (e.g., a visa processing center) to use their own IVR applications. It permits them to manage incoming calls and automate their workflow. The custom IVR application communicates with PortaSwitch via the call control API.

For instance, your customer, a visa processing center, develops an IVR application to announce visa status to callers. When a caller dials the access number, PortaSwitch sends the call to the IVR associated with that customer. The IVR prompts the caller to enter their registration number, then retrieves their visa status from the external database and plays the corresponding IVR message.

Turn on the toggle to enable the feature.
