CHAPTER72 Configuration Parameters Reference
Mediant 800 Gateway & E-SBC | User's Manual
Parameter Description
1. If you configure a value for the xferPrefix
parameter, the value (string) is added as
a prefix to the number in the Refer-To
header.
2. This called party number is then manip-
ulated using the Destination Phone Num-
ber Manipulation for IP-to-Tel Calls
table. The source number of the trans-
ferred call is taken from the original call,
according to its initial direction:
✔ Source number of the original call if
it is a Tel-to-IP call
✔ Destination number of the original
call if it is an IP-to-Tel call
This source number can also be used as
the value for the 'Source Phone Pattern'
field in the Destination Phone Number
Manipulation for IP-to-Tel Calls table.
The local IP address is used as the
value for the 'Source IP Address' field.
Note:
■ This manipulation does not affect IP-to-
Trunk Group routing rules.
■ The parameter is applicable only to
digital interfaces.
'Use Endpoint Number as Calling Number Tel-
to-IP'
epn-as-cpn-tel2ip
[UseEPNumAsCallingNumTel2IP]
Enables the use of the B-channel number as
the calling number (sent in the From field of
the INVITE) instead of the number received
in the Q.931 Setup message, for Tel-to-IP
calls.
■ [0] Disable (default)
■ [1] Enable
For example, if the incoming calling party
number in the Q.931 Setup message is
"12345" and the B-channel number is 17,
then the outgoing INVITE From header is
set to "17" instead of "12345".
Note:
■ When enabled, this feature is applied
before routing and manipulation on the
source number.
■ The parameter is applicable only to
digital interfaces.
'Use Endpoint Number as Calling Number IP-
to-Tel'
epn-as-cpn-ip2tel
[UseEPNumAsCallingNumIP2Tel]
Enables the use of the B-channel number as
the calling party number (sent in the Q.931
Setup message) instead of the number
received in the From header of the INVITE,
for IP-to-Tel calls.
