##### To Edit a SIP Listener

1. In the Developer profile, expand the Configuration, SIP Service, and SIP Listeners nodes.
2. In the Cluster and Enterprise profiles, expand the Configuration node, select the required configuration, select SIP service, and then select the SIP Listeners node.
3. Select the listener you want to edit.
4. Edit the SIP Listener General Settings as follows:

   - Name: You cannot edit the listener name.

   - Listener: Remove the check from the Enabled box if you do not want to enable the listener when the server restarts.

   - Network Address: Enter 0.0.0.0 if you want the listener to listen on all IP addresses for the server, using a unique port value. Otherwise, type a valid IP address for the server.

   - Listener Port: Enter a unique port value if the Network Address field is 0.0.0.0, or the desired port value if you are using another IP address.

   - Transport Protocol: Change the network protocol used by the listener, if necessary.

5. Click the SSL tab and edit the SSL settings as follows:

   - Client Authentication: Check this box to force clients to authenticate themselves to the server when using this listener.

   - Certificate Nickname: Enter the name of an existing server key pair and certificate.

   - SSL3/TLS: Check the security protocol(s) to be enabled on the listener. Check either SSL3 or TLS, or both.

   - Ciphers Suite: Check the cipher suite used by the protocol(s). To enable all cipher suites, check All Supported Cipher Suites. You can also enable individual cipher suites.
