voip.ms + Linksys PAP2T + X-Lite

I have been using voip.ms as my VoIP provider now for a few months and have a few clients using them. Loving the pay as you go model.

There are a few little challenges I have had on the way to have everything running smooth for my clients so they can have a trouble free experience, and a dirt cheap phone bill to boot!

First thing was, when setting up extensions, you have to make sure that ALL extensions are using the SIP servers, eg: sip.ca1.voip.ms

If you have them on separate servers, the extension to extension phone calls will not work. These timed calls are the cheapest (a tenth of a cent or so!), so its pretty important to get it working!

Next was the Phone Adapters I have been using for my clients:

The Linksys PAP2T

The phone adapter would work fine for a "while", then it would not accept incoming calls. Outgoing calls were fine though...

What was needed, is a tweak of the default factory settings. Specifically, log into the adapter, go to the Advanced View, then Ext1.

Set - NAT Mapping Enable: Yes

Set - NAT Keep Alive Enable: Yes

Once this was done, incoming and outgoing calls worked, and the adapter didn't go "offline" for the incoming calls.

X-Lite

With this free SIP softphone, I have had success with the following settings:

• In X-Lite - goto SIP Account Settings - Properties
• Put in the voip.ms User Name
• voip.ms password
• Use the same voip.ms for Authorization user name
• Domain - use your preferred voip.ms server
• Tick - Register with domain and receive incoming calls
• Tick - proxy - Address - use your preferred voip.ms server

Linksys/Cisco SPA921 phone is SIP compliant - sitting next to Linksys PAP2TLinksys SPA921

The Linksys/Cisco SPA921 is a cheap, 2 line SIP phone for desktop use. Settings are very similar to the PAP2T. The more expensive units have more lines, fancier LCD display, and an ethernet bridge, so you don't need 2 ethernet ports at the desk. This would be a fine SIP phone for 99% of users. Good news this puppy can be had for less than $100CAN, and isn't locked into to any vendor specific system since it is SIP compliant!
