Totally agree. We had our Cisco CCIE VoIP verify our dial plan before we deployed it. I do agree with Walt that 7-digit dialing is a good thing. It is scalable. Do use translation pattern for your 5-digit dialing. <br><br>Syed<br><br>> Date: Fri, 12 Feb 2010 18:06:52 -0500<br>> From: jason.aarons@us.didata.com<br>> To: moody@arizona.edu; cisco-voip@puck.nether.net<br>> Subject: Re: [cisco-voip] Dial plans<br>> <br>> You really need to look at your DNs/DIDs and map it out carefully. That<br>> said my generic advice is put 10 digit DNs (or E164 if intl) everywhere,<br>> then setup 5-digit local translation patterns. This allows Unity<br>> UM/UCCX to work across multiple sites.
