Asterisk/Trixbox and Laptop/Cordless Phone

metallica1973 · 02-06-2008, 07:02 AM

I currently have Trixbox/Asterisk running at my SOHO. I frequently travel to client sites throughout my region for service calls. I have been doing a lot of reading about SKYPE - Peer2Peer VOIP calling and was wondering if anybody know of a a method of connecting a cordless phone to a laptop that I would be using out in the field, for example

http://www.voipan.com/voip-phones/

and forward any incoming calls from my Asterisk box to my laptop and then to my cordless phone. I am sure what I would need some sort of Linux based Client software to connect to my ASTERISK box at my SOHO to be able to get this to work. Can someone point me in the right direction? Here is a visual picture of what I want to do:

Does it have to be an actual cordless phone?

If you used, say, a Bluetooth headset (your laptop might already have a BT radio) you could then simply use that as an audio source for the Skype client software running on the laptop. This seems like it would be easier than trying to support what is likely a proprietary device (the cordless base station) under Linux, and would certainly be cheaper (you can get a BT headset and USB dongle for ~$30 online).

What I want to do is connect to my Asterisk box via a client if I need it, establish a connection the connection and call or have calls routes to my Phone on my laptop via Peer to Peer. Does that make sense? The reason that I want it to be cordless is because of the amount of work that I do onsite.

What if I simple created a VPN to my network and then had my wireless phone simple connected through my laptop point to my Asterisk box at my office?
kinda like this:

PHP Code:



Asterisk Box - 192.168.10.2/27
    |
    | 
    |
Firewall/VPN Gateway
    |
    |
    |
Montana, USA
    |
    |
    |
Laptop/Client VPN
    |
    |
    |
Cordless Phone Base attached to laptop - 192.168.10.4/27
    |
    |
    |
Cordless Handset

I would create an extension for tech_support(ext 200) and make the ip address of the laptop static in VPN dhcp pool and then calls would route to the laptop via VPN and vice versa. I wonder how the call quality would be? I would be at the mercy of the network that I am connected too! I would be lucky if there was QOS que for voice but it would have to be on the subnet that I am using my laptop on. Any feedback would be appreciated. Here is an article to support my post:

I am going to give this a try:

purchase a low-end wireless phone such as a:

http://www.voipsupply.com/product_in...oducts_id=1525

use the clients wireless access point or use my laptop as a AP and have it assign my ip phone an ip address. so :

PHP Code:



Internet 
    | 
    |   
    | 
Client Site 
    | 
    |  
    | 
Client AP 
    | 
    | 
    | 
My wireless phone

or

PHP Code:



Internet 
    | 
    |   
    | 
Client Site 
    | 
    |  
    | 
Laptop as AP/DHCPD server  
    | 
    | 
    | 
My wireless phone

I think using my laptop as a AP/DHCPD server is the best solution. I am wondering how the call quality will be given that I have no control over QOS.
