# SPA112 - Fax Settings

To configure the SPA112 ATA device with the Hosted Network VoIPNow platform you can follow the steps below, this covers a few extras that we have found helped improve the experience with the ATA devices for majority of our customers.

### **Step 1. Configure the Extension details**

On first login to the device you should be presented with a quick setup page (below is an example), on this page you need to input a few bits of information. Specifically the extension username and password, along with the SIP Server.

**i. Proxy:** Set this to **"sip01.mhn.net.au"**\
**ii. Display Name:** Set this to be what you have named the extension in VoIPNow\
**iii. User ID:** This is the **"xxxx\*xxx"** number of the extension, this can be found on the extension summary page in VoIPNow\
**iv. Password:** This is the password you set when creating the extension in VoIPNow

### Step 2. Configure additional settings

We have found that there are some additional settings that need to be adjusted for the ATA to function correctly with our system. Adjust the settings in the ATA to match the settings below, everything else not mentioned can be left as default.

Go to the **"Voice"** menu and select **"Line 1"** from the left, on the page that loads adjust the following settings:

**i. Network Jitter Level:** very high\
**ii. Jitter Buffer Adjustment:** no
