DHCP Pause on 5.0SP1

[karkan]

Has anyone tried this new update to see if it solves the problem?

It isn't a problem as such, it's more that they have come in to line with the standards, so they wont be changing it back.

The "issue" makes a mention in the release notes for 5.0 SP1 PR1, but only as much to tell you to read the KB article on MOL.

the problem isn't that it doesn't connect at all which would be the case if the tagging was incorrect though, it is just that the 53xx series of phones take 5 minutes to get an IP address

Just read that someone found that by removing DHCP option 6 from the Mitel DHCP scope resolved issue.
Option 6 is DNS servers.   Issue may be related to having multiple servers in DHCP Option 6 scope.

Hmm, ok, will have to give that a go on Monday and see what happens. Pity I didn't see this yesterday as I had the perfect lab situation to try this in!

We have experienced the same on an CX that was upgraded from MCD 4.0 to 5 SP1. But only on two new phones that were placed after the upgrade. A 5340 and a 5312. They upgraded perfectly and worked for a while. A couple of minutes to be exact. The only way we got them working back again, was by setting the IP settings by hand. The strange on this is that on this site there are other 5312 and 5340 (running before the upgrade) and they still work fine with dynamic settings.

It concerns a site different Vlans (1 data, 2 voice).
