What is qualify in asterisk

The most important parts are the username and password for registration, plus the address of the Asterisk server with which you wish to register. Figure shows a sample configuration for the X-Lite client. Be sure to modify the values of the fields to reflect your configuration. The display name is the string that will be used for Caller ID. The username and authorization user are used for authentication, along with the password.

After entering all this information, verify that Enabled is set to Yes , and then close the configuration menu. X-Lite will then register to Asterisk. Many SIP phones, both soft and hard, are multi-line phones. This means they can accept multiple incoming calls at the same time. Thus, to test your X-Lite soft phone you can simply call yourself, and the call will loop back from the Asterisk server and onto line two of the client. To call yourself, dial extension It may also refer to music or prompts from the PBX.

I have been doing a lot of research on how to do keep alive on the sip sessions , but from what I understood , if we use the qualify on the sip trunk , it prevent the incoming from reaching the trunk if it is marked as unreachable , but what I need to understand what effect will it have on the active calls , do asterisk terminate the calls automatically since the out trunk is unreachable.

The setup that I mean, If you have an incoming trunk [ used to do inbound routes so I can redirect a call to another number , using outbound trunk [ if I put qualify on the out trunk , how will asterisk behave??

It will only do so if the underlying problem causes a re-invite e. In that case, the resulting BYE transaction will probably also fail, leaving the session down for Asterisk, but up for the peer.

The qualify and active calls are completely unrelated and do not impact each other. All answers i have found did not fully resolve my issue, and i hope someone has some suggestions. Qualify does not result in the address changing to unspecified.

This will happen if the registration expires. Are these peers registering to Asterisk? Ok so after some searching if did notice a few things, the peers that have the most problems with losing their IP address to Unspecified seems to have a direct relation to the expire time.
