Dialing Plan configuration Page 205 of 258
•Set the destination code for the VoIP trunk to 30 (retain all digits) or 34 (remove first digit). For example, BUID dialout = 342XX.
The VoIP route destination codes 30 (no digits dropped) and 34 (1 digit dropped) route any call that starts with 30 or 34 out of the system over the VoIP trunk to the main office.
The main office access code length is still 0.
•Assign the telephones registered to the SRG (IP Phones or analog
The users in both the main office and the SRG dial only the DN for all telephones in the main office and the SRG in both Normal Mode and Local Mode.

Option 2: DN ranges in the main office and SRG overlap; DNs for SRG IP Phones are the same in Normal and Local Mode
In this configuration, the SRG DNs overlap with the main office DNs. However, since SRG does not support Vacant Number Routing (VNR), a user registered to the SRG must dial a destination code before the main office DN to call a main office telephone.
To call an SRG IP Phone in either Normal or Local Mode, SRG and main office users need to dial only the DN for the SRG IP Phone. SRG IP Phone calls are forwarded with the main office Private Network ID/destination code appended to the BUID, which allows the call to flow to the VoIP trunks for the main office.
This configuration is not a true CDP dialing plan. A destination code is added by the system to properly direct the SRG IP Phone calls, since the start digits of the DN are not unique for SRG and main office users. Users dialing a telephone registered at the main office must dial a destination code before the main office DN. This plan allows all systems on the network to appear to be available within a range of numbers.
