Generic SIP Endpoints

Restrictions

Non supported phones can not be automatically configured nor be configured with the pascom menu on the endpoint.

Remote CTI control via the pascom client is only possible in a restricted form.

Endpoint Requirements

In order for a SIP device to operate with the pascom server, the following functions are necessary:

• SIP via TCP/TLS (encrypted signaling)
• SRTP (encrypted voice data)
• Outbound Proxy (send data via the Session Border Controller)

Preparation and login data

SIP TLS and SRTP

Read the SIP endpoint handbook regarding how to activate SIP TLS and SRTP. This could involve multiple setting configs.

Create a new Basic Configuration Template

The next step is to build a new basic configuration for the SIP device. To do this, go to the pascom WEB GUI on Devices > Basic configuration

Duplicate the basic configuration Empty Generic Profile and give it a name e.g. My Yealink Devices. Select the new basic configuration and click on Edit > Configuration.

You have to adapt the following code part to your device-parameters. The listed variables are used to automatically fill in the correct login/server data.

{{!-- This is a example template -}}

{{!-- Please clone and overwrite this Profile -}}

{{!-- use regular expression to match a request uri to a template snipped -}}
{{!-- a empty template output (i.e. no if_regex matched) will return a 404 response-}}


{{!-- this "if" block catches request directly to the provisioning url (/) -}}
{{#if_regex "/provisioning/ee[0-9a-f]+/?$" http_path}}
You requested the example generic template.

Please try two other routes:

- append /example.cfg for a example provisioning file
- append /info to the url to see a list of all variables.

{{/if_regex}}

{{!-- requests ending with .cfg (e.g. /y02384.cfg) will be handled here -}}
{{#if_regex "\.cfg$" http_path}}

sip username = {{{013pee_username}}}
sip password = {{{013pee_password}}}
sip host = {{{httpip}}}:5061;transport=tls
sip domain = {{{cs_domain}}}

{{/if_regex}}

{{!-- here, each request ending with /info will be answered -}}
{{#if_regex "/info$" http_path}}

Variables:
----------
{{#each this}}
{{@key}} => {{this}}
{{/each}}

url parameters:
----------
{{#each http_params}}
{{@key}} => {{this}}
{{/each}}

{{/if_regex}}

Save the basic configuration.

Apply Jobs

After saving your changes, an entry will appear in the job box (top centre of the window). Start the job by clicking apply or the green tick.

Create/Add the SIP Device

Insert under Devices > Device list a new device of type IP-Telefon: Hersteller beliebig oder Softphone. Now select the new basic configuration you created earlier (My Yealink Devices).

Under the tab Assign you give the SIP device an user. Finally save!

Provisioning on the SIP Device

Check the IP Device in the device list and go to Action > Provisioning URL where you can copy the provisioning URL to the clipboard.

Each SIP device has its own web interface. How to get there, please refer to the instructions of the respective manufacturer. The Provisioning URL usually has to be set in the Servicing settings of the device at the server URL. After applying the changes and a restart / reboot of the device, the settings are automatically transferred to the device via the provisioning URL.

Test Call

On the SIP endpoint, please dial *100. This should call the pascom Voicemail box and you should here the mailbox prompts.
