Linksys PAP2T Install Guide

The Linksys PAP2T is a low cost Analogue Telephone Adapter that offers 2 ports allowing you to connect 2 phone lines to 2talk. It is widely available from various suppliers in New Zealand. If you wish to connect a fax machine to 2talk then do NOT use the PAP2T though as it does not support the T.38 protocol which 2talk require for reliable fax communications. If you try to send a fax through the PAP2T to 2talk it will always fail. The PAP2T however is very suitable for voice communications. If you require Fax support then you should use the Linksys SPA-2102 or SPA-3102 models which offer good fax support.

Also, be aware that the PAP2T is not a router, does not offer any QoS and you will need a spare ethernet port on your home router to connect it up. Some DSL routers only have 1 ethernet port, so you may need to purchase a switch/hub to use the PAP2T in this case. Again, we would recommend the slightly more expensive SPA-2102 instead if you do not have a spare ethernet port.

Below are detailed instructions on configuring the PAP2T to work with 2talk’s service:

1. Reset your PAP2T to factory default settings

If you purchase a second hand PAP2T or one that has been setup to work with a particular carrier then the safest bet is to reset the settings to the factory defaults so that you start with a clean slate and can be sure that some previously entered setting is not causing you a problem. To reset the PAP2T to factory defaults follow these steps:

The PAP2T should now have been reset to factory default settings.

2. Get access to your PAP2T web interface

3. Upgrade firmware (optional)

Your PAP2T may work well on it’s current firmware, but it is always a good idea to upgrade the firmware on your PAP2T to ensure that you are running the latest recommended firmware on it. Upgrading the firmware is relatively easy with the PAP2T.

4. Getting Admin access on your PAP2T

You need to get administrator access to change many of the settings of your PAP2T to do this go the web interface and click on ‘Admin Login’ followed by ‘Switch to advanced view’

5. Changing your System Settings

6. Changing your SIP Settings

(Changing the above will allow your PAP2T to recover from registration failures more quickly.)

(The STUN settings should be optional. Your PAP2T should work fine without STUN enabled, so you can enable/disable these settings if you are having issues registering.)

7. Changing your Provisioning Settings

8. Changing your Regional settings

If you wish to support the New Zealand Tones for your phones and set the date/time then you can setup the following. There are a lot of settings here that are not strictly necessary for a functional phone, but if you wish the PAP2T to behave similar to a Telecom landline then you are best changing the settings on this page.

9. Configure each of your Lines by clicking on the ‘Line 1′ or ‘Line 2′ tabs

(Setting the jitter level to extremely high will add extra latency to the call but will make the voice quality more reliable over most broadband connections. Unless you believe your internet connection is very stable and does not suffer from high latency or latency variations it is recommended to keep this level extremely high)

NOTE: Since the 2talk FAX service requires that the customer device support the T.38 fax protocol for reliable IP fax communications and the PAP2T does not currently support T.38 – you will not be able to get a fax machine working through 2talk using the PAP2T device. We recommend instead you purchase a Linksys SPA2102 or SPA3102 if you wish connect a fax machine to 2talk which both support T.38 and are known to work well with 2talk.

Troubleshooting Tips

If you are still having problems getting your PAP2T to register with 2talk then you can try disabling or enabling the STUN settings as mentioned earlier.

Another thing you can try is changing your SIP Port from ‘5060′ to ‘50600′ in the SIP Settings under each line

Another thing you can try is to change the ‘Proxy’ and ‘Outbound Proxy’ from ‘’ to ‘′ in the Proxy and Registration settings under each line
