Cisco FXO with Asterisk still getting a lot of play

I keep an eye on my logs and for as long as I can remember this post has been the most popular: It’s funny that almost 3 years later very little has changed.  I’m running Trixbox CE now but the configuration is still pretty much the same.  I’m pretty happy with how TB has […]

Arc express attendant console

It’s been a while since I looked at what was formerly known as the Cisco Attendant Console. Color me unimpressed. I found the new version’s install process to be tedious mainly because it’s java based. Key buttons would disappear repeatedly during the install and I had to reboot several times. The original promise of java […]

SIP to Skype finally, with some caveats

Gizmo5 is finally the one to break the Skype barrier.  They have a new service now called OpenSky (har) that is essentially a proxy between Gizmo’s SIP network and the Skype network.  I imagine they’re doing something like the non-free Skype Asterisk channels that have been out for a while.  This is cool but it […]

TrixBox CE and chan_sccp_b

Once again, I’ve moved the in house phone system.  I was running into problems with the virtual version I had running for the last couple of months.  It worked pretty well most of the time but the clock was continually out of sync and that caused other problems on occasion.  We had one instance of […]

Going Independent

It’s official, I’m going independent.  I know, I probably could have picked better market timing.  I think we’ll be getting a bump in the next month or so though and this year might turn out ok.  Time will tell. In the meantime, I need to find some contract work!  I have a number of opportunities […]

Cisco Servers? Seriously?

I’ve been hearing this rumor for a while now that Cisco is getting into the blade server business.  I’m having a hard time with this being a smart move but I can see the reasoning.  Om posted about the latest rumors today and I think he hits on some important points. It’s not like making […]

CVoice v.6

I’ve been graciously receiving CiscoPress books for review for a while now so it’s about time I actually, you know, review one.  First up is the newest CVoice book: I’m going through a re-cert process right now but I’m also trying to head towards the CCVP.  CVoice is one of my required tests for both […]

Asterisk trunks and order of precedence

Well, I’ve learned something that should have been painfully obvious.  I had the following configured for that SIP trunk to the Cisco router I mentioned: context=from-internal allow=ulaw disallow=all dtmfmode=rfc2833 host= insecure=very ipaddr= port=5060 type=peer The codec is defined by the “allow” statement.  If you put a “disallow” after the “allow” it will negate the allowed […]

488 – Not Acceptible Here

I went forward with the Server 2003 R2 install and then added VMWare Server 2.0.  Trixbox installed very easily and quickly and I added chan-sccp-b using these instructions.  It all went together very well and once I remembered all the places my old config files had old IP’s (I copied over the sccp configs) I […]

Microsoft OCS 2007 R2 – Has the war begun or is this just a skirmish

Stacey over at GigaOM put up Microsoft’s press release about R2 today.  R2’s bringing some much needed feature depth to OCS including better attendant handling, very basic call queueing, dial in audio conferencing and some SIP trunking improvements.  However, this isn’t the “big one”.  R2 still misses some very critical components.  E911 is still missing.  […]
