SIP Options can be enabled or disabled for each SIP Server. By default, SIP Options is disabled.

• SIP Server Name – A name for this SIP Server.

• Enable SIP OPTIONS – Enable or disable this feature for the selected SIP Trunk group.

• SIP Options Interval – How often, in seconds, the server sends a “keepalive” message to this

enabled SIP trunk group. The default interval is 30 seconds.

• Number of Retries – If MaxCS receives no 200 (OK) response, the number of times a “keepalive’

message should be sent. After these retries, if there still has been no valid response, then MaxCS

marks all SIP trunks in the group as Not Ready. The default number of attempts is 5.

• Retry Interval – While a SIP trunk group is in a Retry state and is not receiving a valid response,

how often MaxCS should send another “keepalive” message to the SIP server. The default interval

is 2 seconds.

• If MaxCS does not receive a SIP 200 (OK) message after the set number of retries, it then sets all

SIP trunks in that group to Not Ready.

Step 12: Create a SIP Trunk Profile

Different SIP service providers may support different ways of sending a caller ID. To provide callees with a

more accurate caller ID, you can create a SIP Trunk Profile for a particular service provider, when necessary.

Otherwise, a default profile is used. Once you have created a profile, you can select it in the SIP Trunk

Configuration panel.

1. In the SIP Trunk Configuration dialog box, click the SIP Trunk Profile button on the right.

2. Edit the fields as necessary and click OK. (Refer to the following table for descriptions of these fields).
