Chapter 11. SIP Traffic

Port

Enter the port number of the external SIP proxy.

If no port number is entered, the Telecommuting Module will make a DNS query for an SRV record. If a port number is entered, it will query for an A record.

Gateway

Enter the gateway for the external SIP proxy.

You can select which default gateway should be used for requests sent to this SIP proxy. If you select "-", the requests will be sent to the SIP Default Gateway.

Delete Row

If you select this box, the row is deleted when you click on Create new rows, Save, or Look up all IP addresses again.

Create

Enter the number of new rows you want to add to the table, and then click on Create.

tel: URIs

tel: URIs is a different URI scheme than the user@domain scheme, where the URIs contain only the phone number itself, and the SIP server is expected to know what to do with them.

The Telecommuting Module has no built-in support for tel: URIs itself, but if your outbound proxy can resolve them, you can have the Telecommuting Module send them there.

You can select to Send requests with tel: URIs to outbound proxy. If you entered a SIP server to receive requests from all domains in the Outbound Proxy table, this is also where all tel: URI requests will be sent. You must ensure that this SIP server will know how to handle these requests.

If you have no access to a SIP server which handles tel: URIs, you can instead select to

Reject requests with tel: URIs. In this case, when the Telecommuting Module receives a

request with a tel: URI, it will respond with the code 416.

Save

Saves the Routing configuration to the preliminary configuration.

Cancel

Reverts all of the above fields to their previous configuration.
