Chapter 10. SIP Services

Select if "%20" should be converted into a whitespace or preserved in URIs.

Strip ICE Attributes

Some SIP clients, like Microsoft Communicator 2007, seem to prefer ICE "a=candidate" attributes in SDP over other information, and it doesn’t perform STUN tests as it is supposed to in order to verify the connection. This may sometimes result in no media.

A way to avoid this is to make the Telecommuting Module remove these attributes for all requests.

Ports and the maddr Attribute

The maddr attribute is used to point to a specific IP address, regardless of what the domain/IP address in the main URI should point to. This attribute only applies to the domain/IP address part according to RFC 3261, and other parameters in the original URI (like the port and transport) will still be used. However, some user agents expect that the maddr attribute will reset other URI parameters.

Select if the Telecommuting Module should use the original URI parameters (as is defined in RFC 3261) or if the port stated in the original URI should be ignored.

Keep User-Agent Header When Acting as B2BUA

Usually, when the Telecommuting Module acts as a back to back user agent (B2BUA), it replaces the original User-Agent header with its own. This might cause problems if the other endpoint chooses what to do based on the User-Agent field and what is known about different user agent capabilities.

Select if the Telecommuting Module should rewrite the User-Agent field or not.
