  Mediant 500L Gateway & E-SBC 
Parameter  Description 
  [1] Copy after phone number manipulation = Copies the called 
number after manipulation. The device first performs Tel-to-IP 
destination phone number manipulation (i.e., on the SIP To 
header), and only then copies the manipulated called number to 
the SIP Diversion header for the Tel-to-IP call. Therefore, with 
this option, the called and redirect numbers are identical.  
  [2] 
Copy before phone number manipulation = Copies the called 
number before manipulation. The device first copies the original 
called number to the SIP Diversion header, and then performs 
Tel-to-IP destination phone number manipulation. Therefore, 
this allows you to have different numbers for the called (i.e., SIP 
To header) and redirect (i.e., SIP Diversion header) numbers. 
Note: 
  If the incoming ISDN-to-IP call includes a Redirect Number, this 
number is overridden by the new called number if the parameter 
is set to [1] or [2]. 
  You can also use this feature for IP-to-Tel calls, by configuring 
the parameter per IP Profile 
(IpProfile_CopyDest2RedirectNum). For more information, see 
Configuring IP Profiles on page 438.

[ReplaceCallingWithRedirectNu
mber] 
Enables the replacement of the calling number with the redirect 
number for ISDN-to-IP calls.  
  [0] = Disable (default) 
  [1] = The calling name is removed and left blank. The outgoing 
INVITE message excludes the redirect number that was used to 
replace the calling number. The replacement is done only if a 
redirect number is present in the incoming Tel call. 
  [2] = Manipulation is done on the new calling party number 
(after manipulation of the original calling party number, using the 
Tel2IPSourceNumberMappingDialPlanIndex parameter), but 
before the regular calling or redirect number manipulation: 
  If a redirect number exists, it replaces the calling party 
number. If there is no redirect number, the calling number is 
left unchanged. 
  If there is a calling “display” name, it remains unchanged. 
  The redirect number remains unchanged and is included in 
the SIP Diversion header. 
Add Trunk Group ID as Prefix

routing settings > trkgrpid-prefix
[AddTrunkGroupAsPrefix] 
Determines whether the Trunk Group ID is added as a prefix to the 
destination phone number (i.e., called number) for Tel-to-IP calls. 
  [0] No = (Default) Don't add Trunk Group ID as prefix. 
  [1] Yes = Add Trunk Group ID as prefix to called number. 
Note: 
  This option can be used to define various routing rules. 
  To use this feature, you must configure the Trunk Group IDs 
(see Configuring Trunk Groups on page 501). 
Add Trunk ID as Prefix 
configure voip > gateway

prefix 
[AddPortAsPrefix] 
Defines if the port number/Trunk ID is added as a prefix to the 
called (destination) number for Tel-to-IP calls. 
  [0] No (Default) 
  [1] Yes 
If enabled, the device adds the following prefix to the called phone 
number: port number/Trunk ID (single digit in the range 1 to 8).
