Configuring SIP Timer Values
Configuring Your System for ITSP Interoperability
Configuring SIP Timer Values
The default timer values 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 103 of Appendix B
.
