Setting up 7910

Hi Folks,

I am looking for a step by step guide to setting up a Cisco 7910 phone on a Trixbox 2.0 beta platform. I have been trawling the internet for bits of information but then I lose track after a while in setting it up. I am quite new at Trixbox and assumptions on some basic knowhow are made in the course of the setup process.

I currently have it up and working but there are a couple of problems. First I do not know exactly what sequence of configuration work made it work. This is worrying as it's a bit flaky for my liking.
The second problem is the 7910 can call a SIP soft phone but the reverse fails.
Whiles other phones can make and receive pstn calls the 7910 fails to get past this hurdle.

Whats the most stable SIP and Skinny images for 7940/60 and 7910?

Hey. The 7940/7960 SIP images are up to 8.x now, but I stopped at 7.5 since that was the last stable one that had all the features I wanted; I know some of the 8.x loads have issues.
As far as the 7910 - I have one of these myself, and in reading around (I have not set it up yet either), that is one of the problems with the Skinny protocol - it can call one way, but not the other. I am going to experiment some myself, and will post more, but from what I've read you've gotten it as "working as it's gonna get".

Hi Julian,

I'm pretty new to Asterisk, but thankfully after a day I managed to get some Cisco 7910s (to appear at least!) to be working properly.

I'm thinking about writing a little how to guide/step-by-step - although I don't really think I have the knowledge yet to actually understand everything I've done.

Are you using Skinny or SCCP?

Here's what I eventually did:

- Fresh install of Trixbox from ISO (just to make it "easier", as this was only a test box)
- Installed SCCP, by following these instructions with a few changes:

What did I do differently? Well here is how I did it:

Checked via "Asterisk Info" my revision - 47264.

#cd /usr/src

#svn checkout http://svn.digium.com/svn/asterisk/branches/1.2 asterisk-1.2 --revision 47264

[I skipped some of the other steps, as I couldn't see the relevance?]

I can't remember if the source downloaded into the folder asterisk, or asterisk 1.2. For that reason you'll have to customise it to your download. I also followed the corrections in the 2nd post.

Then I followed the SCCP instructions, that went fine.

To configure it, I started with this tutorial:

Although of course, I have a 7910 - so modified appropriately. For ages I only had inbound calls - outbound calls just got a busy tone on the first digit dialed! I have seen loads of people suffering that problem. It all (at least for me) related to my "context" setting - set this incorrectly and it just doesn't work properly.

As I said, I'm a newbie and am just trying to understand how the dialplan/context works (Trixbox/freepbx kept me a bit sheltered!) - I set it to "from-internal" and it worked fine. The only weird thing is for dialing out everything but internal calls it has about a 5 second delay before it actually connects... probably something to do with the wrong context setting.

I know this threads old now but I received a pair of 7910s the other day and I've got them working both inbound and outbound calling, and I've thought about getting a third. They make nice simple and cheap single line phones, and I like the cisco phones. I couldn't find much about getting them to work but managed to figure it out in the end.
