Failing to call some extensions in a cluster.

[Tinos]

Hi all.

I have two 3300s that are clustered.3300(A) can call all the extensions on 3300(B) however 3300(B) can call most of the extensions on (A) except for 5 extensions that display INVALID when being called.
These extensions exist and are on the same extension number range with those being called successfully.
What could be causing this and how can it be fixed?
Thank you.

are the extensions listed as "Local Only"?
at the maintenance commands type "Locate number XXXX"

is your numbering plan set as 4-digits? if so, is ALL of your extensions set as 4-digits - and also you cluster IDs.

I don't have any Local Only extensions. All extensions are 4 digit length.
CEID is 6 digits.
Locate number XXXX on the 3300 were it exists returns positive but on the other 3300 it cant be located.

Locate Number XXXX tells you what exactly

It should tell you that it is an RDN with CEID Digits cccccc

Does it?

Do those numbers clash with any of the cluster elements or routing digits?

I ended up adding the extensions in the ARS digits dialled explicitly.
