Mitel MiVoice Business/MCD/3300 / No Ringback on SIP Trunks
« on: April 12, 2016, 11:50:06 AM »
I recently switched over to SIP trunks from PRI, after a couple of hiccups the only issue left is that we don't always get a ringback when we dial out. Sometimes it works and sometimes it doesn't. I am using an MBG and did some trace routes to send to SIP provider and they are telling me they are sending the SIP 180ringing back to the MBG. Any help will be appreciated. Thanks
