Very well thought out but, as they say, no one is perfect. That’s why there is all of us to annotate the little caveats that crop up along the way.

The tip?

MAKE SURE nat=no in your sip.conf (or in the extension dialog for freepbx) even if you are using nat for your asterisk server or trunks. It causes havoc with the cisco phone.

Hi, is it possible to change the VLAN from a 7940/7960 IP phone? I already try it with the cisco cable (blue), with telnet and I couldn´t connect the integrated switch. Have anyone a idea?

Hi, This is very helpfull artical. However our problem is that we want to install SIP firmware 8.5 on Cisco 7960 phone but it never helps. Even i put all the extracted files in the TFTP folder but when phone boots, it doesn’t grab all the files and always keep trying. I follow alot of search, these two looks relevant the one i’m at and the other one is here:
http://www.syednetworks.com/configure-cisco-7960-with-sip

But so far nothing helps.
Please let me know how can i install SIP 8.5 version on my Cisco 7960 phone. Thanks

Can you help with this
as well as some helper files to ease the transition (files that the SCCP firmware would normally look for to load the second-stage bootloader)
can you send me that files
Thank you very much

Thanks! Very Helpful – i am still not getting the CallerID passthrough from the PSTN – I get anonymous@192.168.0.45 (my server). Any ideas?

Hey Julian,

Thanks for the post. We actually use these phones (in CallManager config, not SIP) at IBM for our entire phone system in the Toronto lab. Thought you might draw some edification from this post on the subject, though as you say, most of these are reasonably simple tricks:

Thanks for the great tip on using DHCP to point to TFTP server – couldn’t do it through phone Settings. Also the link to XMLDefault.cnf.xml was just what I was looking for, the asteriskguru.com tutorial was no help on this.
