I’m looking at building an Asterisk box in the next little while. The box will be fed by a few POTS lines and a few SIP connections from a provider.
I’d just like to make sure my thoughts will work before starting into a lot of work and $$$
My setup would be pretty much Cisco 7970G on my desk, three Cisco 7960G phones throughout my house, and a Cisco 7920 for roaming about. Yes, for my house but this includes business lines etc.
Asterisk would do auto-attendant, intercom and voice mail features pretty much.
Any surprises with these models, my concept etc? Just a general question but appreciate any feedback before I order these phones etc.
Also note the additional power requirements of the 7970.
I’d be surprised if Cisco didn’t come out with SIP firmware in the future - whether or when this is going to happen would be a question best posed to Cisco pre-sales support or your supplier may be able to fire the question at them.
Now THAT is good news. I was playing with chan_sccp because we’re about to buy 7 7971G-GEs. chan_sccp works well for the most part except when you call a MeetMe conference. Then either the phone freezes or, worse, Asterisk crashes. Now I can buy the phones knowing they will work with Aterisk.
Hopefully the chan_sccp developers will work out the bugs because I’ve found that using SCCP is more resposive than SIP on the Ciscos.
(BTW, Cisco has placed the SIP firmware in their NON-SIP download page.)
I thought somebody might ask me that. The phones aren’t for me, they’re for a wealthy individual that likes to own the latest, greatest and most impotantly, the most expensive . At least I get to play with the phones.
That was supposed to read importantly. What a Freudian slip, ha!
Hi, I just bought a 7970 for private use, but man was I disappointed when I had to buy a servicecontract just to get the phone working with SIP.
Is the firmware downloadable anywhere else on the web? (which doesn´t require a contract).
Best regards,
Andy (With a useless 7970)

You should be able to specify to your supplier/reseller that you want the SIP license with the phone, not the SCCP license. It should then be provided preconfigured with SIP. At least that’s what has happened in the past with other models. That said, the service contract is probably cheaper than the license, though I don’t think that technically gives you the right to download the SIP firmware unless you have a SIP licence (though some Cisco documentation is ambiguous about this).
The Cisco website is the only place the firmware is legally downloadable.
