Análisis de mensajes SIP entrantes
Depending on the SIP provider, the phone number of the caller can be in
different locations in the SIP message. The following options and settings
must be selected and made to determine at which location of the SIP
message the phone number shall be searched.
Two different phone numbers can be transmitted: The actual phone number
of the caller (screened number/network provided number) and a number
self-selected by the caller (unscreened number/user provided number). If a
network provided number is extracted from the SIP message, functions
such as Call Through can be used.
Tipo de análisis
Predeterminado
: Selects an evaluation method for phone numbers which
will work for most providers.
Standard (use From headers as screened-number)
: Selects an evalu-
ation method for phone numbers which will work for most providers. The
user provided number (corresponds to CLIP no screening) of the header
“From“ will be taken over into the network provided number. The phone
numbers can, for example, be used for Call Through via VoIP.
Caution:
If you have selected this option, your telephone and your PBX
are vulnerable to attacks, for example by transmission of a phone
number manipulated by the attacker. Therefore, to protect your
telephone and PBX, assure yourself that the VoIP provider has
integrated sufficient security measures in the number presentation.
Tal y como se describe en RFC3325
: Selects a phone number evaluation
method in accordance with RFC 3325 (http://www.ietf.org/RFC/rfc3325.txt).
This method of evaluating phone numbers is used if the number
presentation is guaranteed by security mechanisms.
