We've been doing VoIP (and FAX) for over 7 years right now and T.38 works great for us (we have guys faxing 80+ pages with no problem) A few things
1. Since we no longer own a WISP (and are bound by a wireless non-compete when we sold several years ago), all of our connections are run over landline circuits (that said, even when we had a WISP, we never ran VoIP over shared best-effort multipoint wireless) 2. We hard-set the T.38 protocol to fax only (we had problems when the protocol would "modulate") 3. We don't run dial credit card machines over VoIP (bad idea) 4. We QoS the @[EMAIL PROTECTED] out of the network (not just our last mile, but we've found the only way to roll out a Centrex solution is to basically "own" the customer's network) #4 is the most interesting to me, as it seems that people are coming to this reality and splitting into 2 camps 1. SIP trunk only providers (so they can set their demarc at the Asterisk PBX) 2. Managed Service Providers (guys who not just do VoIP, but support networks, PCs, computers, apps, everything) It's actually a pretty interesting discussion to get into... -Charles Charles Wu President [EMAIL PROTECTED] cell: 773-457-0718 * office: 773-667-4585 x2500 16W235 83rd Street, Suite A, Burr Ridge, IL 60527 * tel: 773.667.4585 fax: 773.326.4641 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mike Hammett Sent: Sunday, August 10, 2008 8:23 PM To: WISPA General List Subject: Re: [WISPA] VoIP deployments? Fax machines don't run over VoIP either. They just don't, T.38 doesn't really work. ---------- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com ----- Original Message ----- From: "Chuck McCown - 3" <[EMAIL PROTECTED]> To: "WISPA General List" <[email protected]> Sent: Sunday, August 10, 2008 9:30 AM Subject: Re: [WISPA] VoIP deployments? > Businesses cannot run on cell phones.
