SIP Trunking
Programming the Incoming Line Group
1. For SIP trunk programming you start with an ILG and OLG assignment.
2. For ILG Programming create an ILG group (In this example Group Number 8).
3. FB01 - Trunk type- select SIP.
4. FB03 - CO service type- DID.
5. FB11 - Number of DID Digits- number of incoming digits to use from the dialed number to route the
call. Count the number of digits from the least significant digit.
DID routing must be set up to route incoming SIP calls to their desired destinations. That programming is
the same as any other trunk group type. If that routing is not set up incoming INVITEs (calls) will fail.
Note: SIP trunking requires a license for each trunk. No channel group can successfully be programmed
without a license.
SIP trunking is supported by the MIPU/GIPU card only. It can share connections of its ports between
stations and IP telephones and other IPU devices. The IP telephones are the only devices that are can be
assigned equipment number 0000. That is, SIP stations, VM ports, SIP trunks and attendant consoles are
fixed resources. IP telephones do not need to be fixed assignments (unless they are assigned a fixed
equipment number - not 0000).
