Configuring the SPA9000 for ITSP Interoperability

Configuring SIP Timer Values

Configuring SIP Timer Values
The SPA9000 is configured with default timer values that should be adequate in most
circumstances. However, you can adjust the SIP timer values as needed to ensure
interoperability with your ISTP. For example, if SIP requests are returned with an "invalid
certificate" message, you may need to enter a longer SIP T1 retry value.
To view the default settings or to make changes, open the Voice > SIP page, and scroll down to
the SIP Timer Values section. For field descriptions, see "SIP Timer Values (sec) section, " on
page 161.
