This article is written for Telephone, the free application available through the OSX App Store.
Each user has a set of credentials which will be needed to configure each phone. For each phone that you are configuring, obtain the following:
- SIP Address (Address of Record)
- SIP Password
- Auth Username
You can find this information in the user detail pages under the Users tab in the Phone Configuration section.
When you first load the device you'll be informed there is no account information and provided a link to set up your account. On subsequent attempts to set up the software, you will need to select Preferences.
Enter the following information from Step 1 above:
- Full Name > Whatever you would like.
- Domain > Domain
- Username > Auth Username
- Password > SIP Password
The device will attempt to register and will then fail. This is because the software makes assumptions for the rest of your registration information. From here go to the software's preferences. Remove the check from "Use this account" so you may edit the fields and then select the Advanced tab.
Change the SIP Address field to reflect your correct SIP address and then select the Network tab.
Change your Outbound Proxy to "sip.onsip.com"
Now close the window and using the Telephone status drop down change Unavailable to Available. Telephone should register and the program is now ready to use.
In the User portal, click on the "Users" tab. You will see a green "online" notation next to each user with a registered phone.
You should now be able to place and receive calls.
To transfer, during a call hit "t" and you'll be prompted for the target of the transfer. The only transfer option as of this time is blind transfer. You cannot do attended transfers but that feature should be forthcoming.
To place a call on hold, hit "h" (Music on Hold is currently not supported with Telephone), to remove from hold, hit "h" again.
To mute a call, hit "m" and to resume, hit "m" again.
DTMF is RFC2833 by default so you don't have to do anything to get it functioning. Use the number keys on your keyboard and you can navigate.
Telephone also integrates with your Mac's address book. To dial from the address book, the phone number field will require 1-NXX-NXX-XXXX format so you will most likely need to edit the phone numbers. You can also right click to call from your Address Book.
