Mitel MiVoice Business/MCD/3300 / MiVoice Business 8.0 SP3 PR1 connection to MultiTech FaxFinder FF240-IP via SIP
« on: September 07, 2018, 03:20:18 PM »
Has anyone ever successfully connected a MultiTech FaxFinder FF240-IP to a Mitel 3300/MCD/MiVoice Business via SIP trunks? No matter what I try on an outbound fax the call is always rejected with a "503 Service Unavailable" error, no matter if I try T.38 or G7.11 pass thru. Mitel offers no information and neither does MultiTech, at least that I can find. Any help would be appreciated. Thanks!
