MiVoice Office 250/Mitel 5000 / Communication Error-: Default_ScreenSaver5340.spx and TFTP ERR:4 issue.
« on: February 04, 2014, 01:41:37 PM »
This is my first post here and apologise for my lack of technical knowledge. We need a bit of help (we are a reseller)
We have 4 Mitel 5000's installed all networked. All sites had SIP installed from Voiceflex on small Draytek routers. The customer had a VPLS network from Expo-E connecting the sites for voice and data. All worked fine. We recently moved the SIP from the DSL/Drayteks onto their Expo E Network. All good.
The one thing that doesn't work anymore is the remote home worker phones - they cannot connect with the main site that has remote workers - Expo E and the firewall providers insist they have opened up all the necessary ports on their equipment and networks and have tested their routing. They have even (apparently) set up a separate remote worker VoIp V/LAN in addition to the existing voice and data v/lans.
Please help - anyone got any ideas? Could it be down to the ISP filtering traffic ( have also seen a post mentioning MTU sizes) - please let me know if you have any ideas and I can pass this onto our engineers - we have asked Mitel but they are slow to react.
Really appreciate any comments urgently if possible!
Thanks in hopeful anticipation.....
