Obihai OBi110 Administration Manual page 13

When the phone port goes from on-hook to off-hook, in case the user needs to dial * * * to invoke the IVR, the OBi will play
a dial tone for 5 seconds. After 5 seconds the OBi will turn silent and be ready to accept an incoming call to page.
Primary Line
By default, devices which come with an analog (PSTN) line port will use this as the Primary Line for outbound calls made
from the PHONE port and via the OBi Auto Attendant. This means that when you dial a new number using the AA, you do
not need to first dial a service route access code. You can select the Primary Line for the PHONE port and for the AA,
respectively, using the parameters PHONE Port::PrimaryLine and Auto Attendant::PrimaryLine.
Depending on the device model, you may add up to two (2) or four (4) SP VoIP services to the OBi, and attach a PSTN line to
the LINE Port as an additional voice service. The VoIP services can be SIP-based services or the Google Voice service (SIP
only on OBi302). In addition, all device models come with the free OBiTALK (peer-to-peer) service. In this document we
sometimes refer to any one of these voice services as a trunk. A trunk group (TG) is a (comma-separated) ordered list of
trunks. If a TG is selected for making an outbound call, the OBi will pick the first available member in that trunk group for
the call. Up to four (4) TGs can be defined in an OBi (see the section Trunk Groups for detail).
You can make one of the available trunks or TG1 as the Primary Line for outbound calls. The Primary Line for the PHONE
port(s) and the Auto Attendant is configured via the OBi device management web page described herein or the OBiTALK
Device Configuration VoIP Service Provider set-up screen also gives the user the option to select a trunk or TG1 as the
Primary Line. The list below summarizes the choices available for selection as the primary line:

SP1 Service

SP2 Service

SP3 Service

SP4 Service

OBiTALK Service
 1
PSTN Line

Trunk Group 1
When you want to make a call via a service that is not the Primary Line, you will need to dial that service's access code
before the destination number.
The default service route access codes are defined as:

** 1 : SIP Service Provider 1 or Google Voice Service 1

** 2 : SIP Service Provider 2 or Google Voice Service 2

** 3 : SIP Service Provider 3 or Google Voice Service 3

** 4 : SIP Service Provider 4 or Google Voice Service 4

** 8 : PSTN Line Port Service Provider

** 9 : OBiTALK Network
Service route access codes for calling from the PHONE port can be customized if necessary by modifying PHONE
Port::DigitMap and PHONE Port::OutboundCallRoute. Service route access codes for calling via the Auto
Attendant can be customized if necessary by modifying Auto Attendant::DigitMap and Auto
Attendant::OutboundCallRoute.
Note: Occurrences of (Mpli) and pli are substituted internally with the corresponding abbreviated trunk name of the
selected primary line.
