There are two ways for end users to maintain their subscriber settings: via the Customer Self-Care Web Interface and via Vertical Service Codes using their SIP phones.
The NGCP provides a web panel for end users (CSC panel) to maintain their subscriber accounts, which is running on https://<ce-ip>. Every subscriber can log in there, change subscriber feature settings, view their call lists, retrieve voicemail messages and trigger calls using the click-to-dial feature.
To log into the CSC panel, the end user has to provide his full web username (e.g. user1@1.2.3.4
) and the web password defined in Section 6.2, “Creating a Subscriber”. Once logged in, he can change his web password in the Account section. This will NOT change his SIP password, so if you control the end user devices, you can auto-provision the SIP password into the device and keep it secret, and just hand over the web password to the customer. This way, the end user will only be able to place calls with this auto-provisioned device and not with an arbitrary soft-phone, but can nonetheless manage his account via the CSC panel.
You can simplify the login procedure for one SIP domain in such a way that users in this domain only need to pass the user part (e.g. |
As an operator, you can change the appearance of the CSC panel by modifying a couple of parameters in the section www_csc→site_config of the config file /etc/ngcp-config/config.yml. Modify the site title, your company details and the logo to reflect your use case.
You can also enable/disable specific languages a user can choose from in the CSC panel. Currently, English (en
), French (fr
), German (de
) and Spanish (es
) are supported and English is activated by default.
After changing one or more of the parameters in this file, execute ngcpcfg apply
to activate the changes.
Vertical Service Codes (VSC) are codes a user can dial on his phone to provision specific features for his subscriber account. The format is *<code>*<value>
to activate a specific feature, and #<code>
or #<code>#
to deactivate it. The code parameter is a two-digit code, e.g. 72
. The value parameter is the value being set for the corresponding feature.
The value user input is normalized using the Rewrite Rules Sets assigned to domain as described in Section 6.6, “Configuring Rewrite Rule Sets”. |
By default, the following codes are configured for setting features. The examples below assume that there is a domain rewrite rule normalizing the number format 0<ac><sn> to <cc><ac><sn> using 43 as country code.
*72*01000
, and disable it by dialing #72
.
*90*01000
, and disable it by dialing #90
.
*92*30*01000
, and disable it by dialing #92
.
*93*01000
, and disable it by dialing #93
.
*50*101000
, which then can be used by dialing *1
.
*55*0830
.
*31*01000
.
*80*789001000
to call 431000 bypassing block lists.
You can change any of the codes (but not the format) in /etc/ngcp-config/config.yml in the section sems→vsc. After the changes, execute ngcpcfg apply
.
If you have the EMTAs under your control, make sure that the specified VSCs don’t overlap with EMTA-internal VSCs, because the VSC calls must be sent to the NGCP via SIP like normal telephone calls. |
NGCP offers several ways to access the Voicemail box.
The CSC panel allows your users to listen to voicemail messages from the web browser, delete them and call back the user who left the voice message. User can setup voicemail forwarding to the external email and the PIN code needed to access the voicebox from any telephone also from the CSC panel.
To manage the voice messages from SIP phone: simply dial internal voicemail access number 2000
.
To change the access number: look for the parameter voicemail_number in /etc/ngcp-config/config.yml in the section sems→vsc. After the changes, execute ngcpcfg apply
.
To let the callers leave a voice message when user is not available he should enable Call Forward to Voicebox. The Call Forward can be provisioned from the CSC panel as well as by dialing Call Forward VSC with the voicemail number. E.g. when parameter voicemail_number is set to 9999, a Call Forward on Not Available to the Voicebox is set if the user dials |
