Hello Fellow Mitel Techs,
I got me a strange issue, hopefully some one can lend some insight. We have a Teleworker customer at four sites. They are changing over to a new WAN provider. They have both Mitel branded 5330e/5340e's and UC360's at all sites. Two sites have thus far changed to different WAN Providers. The customer is telling me they changed only the circuit and re-configured the router with the new WAN IP info. Upon doing this they noticed all the UC360 were no longer working. The Mitel 5330's and 5340's were just fine and they registered to the MBG with no issue.
Site 1
1) I verified all Teleworker settings on the MBG and had the customer verify on the UC360 that all settings were intact (I even had him export me an XML config and I reviewed)
2) I took a UC360 we have here in the office (Yep, I'm a remote Tech) and imported the XML config and it connected to the MBG no problem. So I Know the config is good on both ends.
3) The customer left the UC360's unplugged over a weekend and on Monday morning plugged them back in and they started working again (The DHCP handed out new IP addresses) Paid no mind to it, I was just glad they were working again.
Site 2
1) Same thing, I checked the Teleworker settings on the MBG and had the customer do so on their end too. (Again, had them export me a config to review)
2) Took our UC360 here in my office and imported the config, worked like a champ. And again, I know the config is good on both ends.
3) This is where I'm at now.....I believe it is IP address related and I've informed the customer to unplug the UC360 and dump the ARP tables on their router and then plug the UC360 back in so that it will pick up a new IP address, and hopefully connect and work. However the customer is reluctant to do so, and asking us to explore other avenues.
What are your guy's thoughts on this?
Thanks,
