Hello list, Slightly off the list topic, but I hope I'll get some help here. Somebody wants me to implement for his project a Cisco based VoIP system. I told him that I specialize in Asterisk based systems, but he is not even aware of Asterisk. The requirement of project is such that chances are slim that this firm will consider Asterisk based system. So I told him that though not experienced specifically in Cisco, if they hire me I'll setup their VoIP on Cisco system. Now I have no previous experience with Cisco systems and don't want to screw up anything. Are they much different than Asterisk based systems? I guess the underlying VoIP technology is the same for both the systems so it shouldn't be hard to set it up on Cisco. Any ideas, suggestions.

I also thought that they should get it from an official Cisco reseller if they wanted support. Maybe at this stage they themselves don't know what they want.

Or maybe not. Decision makers have their reasons and clearly if price was the only reason, Cisco / Avaya / etc. wouldn't still be selling phone systems. I've done enough Cisco installations to tell you it's not all that hard, especially if they are using the latest and greatest software, gateways and IP phones. Set up the UC server on the network, use the web interface to add/configure the gateways, and if you have DHCP setting up the IP phones is pretty much a snap. On the other hand, David is right. Cost of Cisco equipment is one thing, but Cisco requires annual maintenance on all the software and hardware before they will talk to you. We set up a 15-phone Cisco setup in our Florida office. Works well. Then decided to upgrade our 30-phone office here in Wisconsin to Asterisk. Twice as many phones, one-third the cost. Same functionality, but the Wisconsin office has simultaneous-calling and our own conference bridge at no extra cost. The last three years Cisco has been charging over $2000 a year just in the maintenance on the equipment in our Florida office. The boss doesn't want to pay it anymore, so I am right now moving them over to Asterisk. ROI is less then two years. -- Dean Hoover Milwaukee, Wisconsin -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] How different is implementing Cisco based system than Asterisk based system?
I'll keep this all in mind. I don't plan to become a Cisco expert over night. Flirts I'll try to make them use Asterisk. I don't know the details yet. But some of these big organizations don't even want to consider anything other than the proprietary systems.
