Class 3xx Message Processing

Sometimes during negotiation for a connection, status messages about this process will be sent. Here you select whether to forward these to the client or process them in the Telecom- muting Module.

A class 3xx message from a server means that the connection attempt was terminated, but no connection was established, e.g. due to use of the wrong address or service. The Telecom- muting Module as well as some clients can use this information to make new attempts which might have a better chance to succeed.

The choices are Forward all, which forwards all class 3xx messages to the client (which might be able to use this information), and Follow redirects, which means that the Telecom- muting Module itself uses the information and might make new connection attempts. In this case, it will only inform the client when the connection finally is established or the attempt has failed totally.

Normally, the CSeq number of the request is kept when SIP devices follows redirects. In some situations, other SIP equipment might require the CSeq number to increase when the Telecommuting Module follows redirects. Select here if it should do so.
