Phones sitting in discovering mode?

[strupar007]

Hi,

Can someone explain why phones would sit in discovery mode for hours? (discovering ip address"). What does it usually mean?

Thanks

What version CM are you running..?

do you have the phones pointing to the correct IP Address of your DHCP Server where the 46xx file is located. Check your IP's make sure there are no firewalls blocking the phone or ACLS

In our situation it means the phone cannot find it's DHCP and therefore it's config string (which is option 176 for 46XX stations).
It's always a phone that was used in a different subnet before it was moved to a new location.

Usually a <hold>reset cures it...

Discovering can mean all the above.. dhcp scope (avaya 176/242) options don't have the correct mcippadd in there. We use separate voice and data vlans/subnets in our offices and those scopes need to be defined on both. The other issue I've seen with discovering is in that of the remote office. If the WAN link isn't stable enough the phones keepalives are failing. You can teak that on the network region form, but not sure you want to mess with that.
