# Editing the SIP provider

These settings provide the interface between the SIP provider and the communication server. You can enter the coordinates of your SIP providers here and specify the communication parameters to the SIP provider.

## Routing path

- An incoming call follows the routing path: SIP exchange -> SIP provider settings -> SIP account settings -> direct dialling plan -> ...

- An outgoing call via an SIP exchange follows the routing path: ... -> route- SIP provider settings -> direct dialling plan -> SIP account settings -> SIP exchange.

- Each SIP provider has its own SIP trunk group.

## Resources and licences

- Up to 30 SIP voice channels are available for each SIP provider.

- For each SIP voice channel you need an SIP Access Channels licence.

Table 1. General settings
Parameter | Explanation
Network interface | ID of the network interface
Name | System-internal designation of the SIP provider
Trunk group type | Type of exchange connection
Max. incoming calls | No further outgoing calls are routed via this trunk group once the set limit is reached. This is signalled to the caller by means of the congestion tone. This allows you to ensure that lines remain free for incoming calls.
Max outgoing calls | Once the set limit is reached, no more calls are accepted by this SIP provider. This is signalled to the caller by means of the congestion tone. This allows you to ensure that lines remain free for outgoing calls.
Total B channels | Shows the number of available B channels in the case of digital network interfaces.

Table 2. Network interface
Parameter | Explanation
SIP provider | System-internal reference number of the SIP provider
Name | System-internal designation of the SIP provider
Registrar | Enter here the host name of the SIP provider and the port (syntax: <Host name>:<Port>. If you do not enter the port, the standard port 5060 is used. Note: To ensure the host name is resolved, make sure a valid DNS server address is configured in the IP network / IP addressing view.
Primary proxy | Lets you enter the IP address or the host name of the SIP provider's primary proxy server. Syntax: <IP address>:<Port> or <Host name>:<Port>. If you do not enter the port, the standard port 5060 is used. You can also leave the entry blank. The communication server will then attempt to evaluate the proxy address with the aid of an SIP service. Requirement: The host name (not the IP address) is entered under Registrar.
Provider authentication | With several accounts: Each DDI number is linked with one SIP account. You can create and manage the SIP account at the end of this overlay view. With one account: Only one SIP account is needed for several DDI numbers. You can create and manage the SIP account at the end of this overlay view. Without accounts: The SIP access is direct and not via an SIP account. This setting is only relevant if the SIP exchange is not a SIP provider, but a different communication system (see also "Notes on the setting Provider authentication = Without accounts").

## Notes on the setting Provider authentication = Without accounts

Note:

This setting is only relevant if the SIP exchange is not an SIP provider, but a different communication system. Before activating, you need to remove any SIP accounts already assigned.

Tip:

It is preferable to configure a private SIP network using the settings in Private SIP networking ( =uy).

## Working with SIP provider profiles

You have the provision for storing the main SIP provider settings in XML files, managing and modifying these files, and calling up the SIP providers:

- To create a SIP provider profile, configure the settings for a SIP provider, and then click the Export SIP provider profile button. The parameters are exported to an XML file and stored in a temporary directory on your communication system. Depending on your browser settings, the file opens in the browser or you are prompted to save it.

- To create a new SIP provider with the help of a SIP provider profile, right-click the box of the corresponding network interface in the routing overview and select the entry Import SIP provider profile in the context menu.

## Managing a SIP account

To manage the SIP account, proceed as follows:

- To open a new SIP account, click the New button and edit the settings on the Add SIP account overlay view.

- To delete a SIP account, click the recycle bin icon to the left of the SIP account and follow the user prompts.

- To edit a SIP account, click the SIP account reference number and edit the settings on the SIP account overlay view.
