Item Description
Match a Source Host
Name Prefix
• Specify the prefix of a source host name as a call match rule. The specified
source host name prefix is used to match against the source host names of
calls. If the INVITE message received by the SIP trunk device carries the
Remote-Party-ID header, the source host name is abstracted from this
header field. If the INVITE message received by the SIP trunk device carries
the Privacy header, the source host name is abstracted from the
P-Asserted-Identity or P-Preferred-Identity header field. If the INVITE
message received by the SIP trunk device does not carry any of the
previously mentioned three header fields, the host name in the From header
field of the INVITE message is used as the source host name.
• Specify the prefix of a source host name consists of 1 to 31 characters, which
are not case-sensitive and can include letters, digits, underlines (_), hyphens
(-), asterisk (*), and dots (.). An asterisk represents a character string of any
length, for example, t*m can match the source host names tom, tim, and so
on.
Match a Destination
Host Name Prefix
• Specify the prefix of a destination host name as a call match rule. The
specified destination host name prefix is used to match against the
destination host names of calls. The host name in the To header field of an
INVITE message received by the SIP trunk device is used as the destination
host name.
• Specify the prefix of a destination host name consists of 1 to 31 characters,
which are not case-sensitive and can include letters, digits, underlines (_),
hyphens (-), asterisk (*), and dots (.). An asterisk represents a character
string of any length, for example, b*y can match the destination host names
boy, boundary, and so on.
Match a Source
Address
IPv4
address.
Specify a source IP address as a call match rule. The value must be in
dotted notation and can include dots (.), multiplication signs (x),
asterisks (*), and digits, where
x
represents any number between 0
and 9,
*
represents any number between 0 and 255, and
x
and
*
can
appear multiple times in one source IP address. Fuzzy matching is
supported. For example, 100.1.x.3 indicates any IP address between
100.1.0.3 and 100.1.9.3, and 192.*.*.* indicates any IP address
between 192.0.0.1 and 192.255.255.255.
DNS.
Specify a domain name as a call match rule. A domain name is not
case-insensitive and can include letters, digits, hyphens (-),
underscores (_), asterisk (*), and dots (.), with a maximum length of
255 characters. If you provide this parameter, the specified domain
name is used to match against the source addresses of calls, and a
whole-word match is considered a match. For example, if the domain
name is configured as sohu, sohu.com is not a match. However, fuzzy
matching is supported. An asterisk represents a character string of any
length, for example, i*n can match the source addresses ilison,
iverson, inn, and so on.
Server
Group.
Specify the index of a SIP server group as a call match rule.
Configuring coding parameters
The coding parameters of the call route of a SIP trunk account are the same as those of a call route.
For more information about coding parameters, see "Advanced settings."
Configuring other parameters
Other parameters of the call route of a SIP trunk account are the same as those of a call route. For
more information about other parameters, see "Advanced settings."
