Outbound Routes --> Dial Patterns:

Simplest Dial Pattern - using X. will send all dialled digits to sipgate: 

If you also add a Dial Pattern in your Trunk settings, the Outbound Route's Dial Pattern will be applied to the dialled number first followed by the Trunk's Dialling Pattern. 

Set your Outgoing Caller ID:

** Please Note ** It is only possible to set an outgoing Caller ID from a/the number(s) you have on your sipgate trunking account. It is not possible for you to set "any number" as an outbound caller ID with sipgate trunking.

More than one phone number can be used with a single SIP Trunk. 

The phone numbers the Trunk will receive incoming calls with can be chosen in your sipgate account Settings:
- Under the Trunking tab click on the trunk.
- On the right hand side of the trunk's settings click Assign Phone Number to add a single number.
- Choose +Phone Number Block to add a block of three or ten numbers.  

To set the Outgoing caller ID in FreePBX:
- Open Admin --> Config Edit 
- Click on the extensions_Custom.conf file and add the following text: 
[macro-dialout-trunk-predial-hook]
exten => s,1,SipAddHeader(P-Preferred-Identity:sip:${CALLERID(number)}@sipconnect.sipgate.co.uk)
exten => s,n,MacroExit() 

- The number you wish to show on outgoing calls can be selected in FreePBXs settings in the the Trunk Settings ('General' --> 'Outbound Caller ID'), the Outbound Route's settings ('Route Settings' -> 'Route CID') or in the Extension settings ('Outbound CID'). 

The number to be displayed as your outgoing caller ID must be sent to sipgate in the in the E.164 format (i.e. international format without the leading zeros or plus (+) sign) as a new header P-Preferred-Identity: 4420300000000)
