Topic # 129471 17-Sep-2013 10:45 Send private message

Hello everyone,

I have a Cisco 7942G VoIP phone and I would like to use it at home.

I have been trying to find relevant information on how to make it happens, including the necessary equipment and setup procedures, but it has not been successful.

I am writing to seek advice from you all experts.  Hopefully you will help me out.

Thank you.

Ricky

Unfortunately these aren't the easiest of phone to configure, and some settings can't be set without using a TFTP server.

There is a pretty good guide here for configuring one for 2talk. If you use another provider you should be able to substitute the settings.

Step 1) Throw away your 7900 series phone.

Step 2) By a SPA5xx series phone. (Sub $200)

Step 3) Enjoy a nice new phone with much nicer firmware and much much easier auto-provisioning.

Don't even try, its not worth it. Sell it to someone who deploys a lot and get something with autodeploy abilities with VOIP providers like the SPA series.

+1 to all of the above.

The fact you're having to ask how to configure it would suggest to me you'll really struggle to be able to configure it. The best option is to buy something a lot simpler to configure and use.

Those phones are only designed to be used is a CUCM environment. Their SIP firmware is still only designed for a Cisco environment and doesn't work at all well with some aspects of the SIP standard or play nicely with NAT.

Sometimes the truth isn't what people want to hear, but the simple reality is unless you really know what you're doing those phones should be avoided at all costs in a non CUCM environment... I like to think I know what I'm doing some days and still wouldn't go near them!

It's also rather easy to break them as you flash the firmware from SCCP to SIP....

I've had mine working very nicely hanging off an Asterisk box on my LAN - but trying to get it to register to an external SIP provider is a painful and unreliable process.
