Connect PSTN lines using Grandstream GXW-4104

Jun 3, 2009 at 4:24 AM


I bought this FXO device and would like to hear from people who used or is using this configuration. I want to make it as a sip server or something like that, so I can configure CB to connect to it as a Telephone Provider. Please provide me with details on how to configure the grandstream.


Thank you!!

I was able to configure CallButler and the GXW-4104 to answer calls.
Below are some images describing what I've done so far.

Configured SIP Server at profile1 to use the ip of the computer where CallButler is running and enabled SIP Registration.


Make sure the configured channel uses the desired profile.

And at CB I created a telephone provider at Phone Number tab, using the SIP User ID, Authenticate ID and Password from the screen above.

That worked, however at CB it shows Registration Error - 408 Request Timeout. Of course I would like to see "Registered", so if someone knows the reason let me know. 
Anyways, it's working and know I'm trying to make CB route the outgoing calls to the device. Any tips are welcome!
