Remote phone hung on.... "Please wait while upgrades..."

[Hershel]

Anyone seen this before?

Setup a remote phone and it came online while we were onsite but since we left the phone has become hung up on the "Please wait while upgrade are being preformed on the HTML applications on this phone" screen.

Monitoring though Mitel SAD shows the phone as online but it can't make calls.
The other remote phone onsite works fine

It sounds like you are missing a port in Port forwarding or the remote end is blocking the port. Other possibility is the MTU of the Internet connection is too low.

Is this direct port forwarding or using an MBG?

Direct port forwarding.  Odd things is another phone onsite works fine. 

Just to rule out cabling or a physical port issue I have them try the non-working phone in place of the working one and the same things.

So, one phone connects fine.  The other phones seems to connect but get hung up on the "Please wait while upgrades...."

I suspect the issue had something to do with the port forwarding, specifically the ports associated with HTML (3999, 3998)

There is a work around...
Create a new Application Profile
Make sure nothings is under the Applications
Assign the remote phone to it

This bypassed the need to load any HTML applications, problem solved.

No, the problem isn't solved, the problem is bypassed...

The issue is probably with the router on near-end of the phones, it does't know how to handle multiple port mappings (where multiple devices request the same port) correctly or IPS is active. What is the router make and model?
