AT-VP504E FXS 89
Authentication
Information
Authentication information allows you to add some level of security to
the AT-VP504E FXS lines by setting user names and passwords.
Username and Password Syntax
The syntax of the authentication variables is as follows:
"realm1"="username1":"password1";"realm2"="userna
me2":"password2";.."realmn"="usernamen":"password
n";
Note that realm, username and password are enclosed in quotation
marks. For example:
"ABC Inc" = "John Smith":"Hello"
Notes:
If the syntax of AuthUsrPwd is valid, its corresponding
read-only
AuthValid is set to 1; if not, it is set to 0.
The same realm cannot appear twice in the same
variable, or one of them will be ignored.
If a realm is in the general variable and in a port-specific
variable, the port-specific password and username will
be used.
sipUA1Maximum
SessionExpirationDelay
Set the maximun session expiration delay in
seconds. If
sipUA1MustUseSessionTimers is
set to 1, then an INVITE is sent every
n
seconds, where
n is specified in the
sipUA1MaximumSessionExpirationDelay
variable. If an INVITE does not get an answer,
then the call is terminated. This option allows to
detect the end of a call caused by a
communication problem on the network. If
sipUA1MustUseSessionTimers is set to 0 and
the network is cut off between the two
telephones, then it will not be possible to detect
the end of the call, because no end of
communication packet will be received.
Default Value: 60
