This is the Obihai ATA Device(s) advanced configuration guide, which will help you configure advanced routing parameters and configuration scenarios for the OBi Family of Analog Telephone Adapters & Gateways

Overview


In some deployment scenarios, it may be desirable to consolidate a group of DID's under a single SIP registration. This allows you to not only consolidate your DID's, but the way in which those DID's are billed as well. With this method, you have the flexibility to route/assign DIDs as your deployment may require, while taking advantage of additional cost savings in the process.


We've outlined this sort of scenario in this configuration guide for the Obihai family of analog telephone adapters (ATAs) and FXS gateways. As always, should you have any trouble with this configuration guide or need any other assistance, be sure to open a ticket and one of our Engineers will be happy to help you resolve any issues you may be having. For the purposes of this guide, we will be using an Obihai OBi508vs, however this guide can be applied to any Obihai multi-port analog telephone adapter and/or gateway.


Configuring the OBi508vs for DID Routing


Models: OBi202, OBi302, OBi504vs, OBi508vs


(NOTE: The T38Fax support team will need to enable a feature on your Power-T.38 account to support this method of routing. Contact us by email or ticket to request this feature be enabled on your account.)

This guide is designed for Advanced users familiar with number manipulation and pattern matching, if you're uncertain about anything in this guide please feel free to open a ticket and one of our engineers can assist you in configuring your device(s). This guide builds on our additional configuration guides found here, if you're beginning from scratch please ensure to follow the guide that corresponds to your device first and then return here to complete the additional setup. Links are provided at the bottom of each of the Obihai configuration guides to take you here for further/advanced configuration.

1. Select the associated ITSP Profile (we used profile "A") and configure the following options:


X_SpoofCallerID: True (Check the Box)
X_UserEqPhone: True (Check the Box)


Submit your changes, you may need to reboot the device if prompted.

2. Select the SP Service that corresponds to the ITSP Profile above, we used SP1 Service in this example. Here is where we will configure the inbound call route to recognize the called number, and route to correctly route the call to the corresponding interface that your DIDs are assigned to. As a reminder, we are using the following numbers in our example: 18043027000 & 18043027001, with the number ending in 7000 being the primary number on this trunk and is used for registration.


Under "X_InboundCallRoute" we have configured the following route:


{>(@.8043027000):ph1},{>(@.8043027001):ph2}


How does this work exactly? Let's break it down for clarification. Curly brackets { } are used to enclose each rule, each rule is separated by a comma. Adding to the front of the rule specifies that we're performing our pattern recognition on the number being called (Your phone numbers). We've enclosed two additional characters before the number: @. This syntax will match any number of characters before the last 10 digits of the called number (Which will recognize these calls with or without a 1). After closing the parenthese we then simply define which port to send the call to, such as :ph1


See the Screenshot below for an example:

3. Finally, we'll need to also configure an Outbound rule, so that we can both send and receive faxes.



For line one, add: {(Mpli):pli(18043027000>$2)}, to the Front of the existing values.
For line two, add: {(Mpli):pli(18043027001>$2)}, to the Front of the existing values.


NOTE: The trailing comma is essential, and separates additional rules provided by default.Obihai Outbound Route Configuration


That's it! Your calls should route accordingly! Additional lines can be configured by duplicating the process found in this guide.
