Solved Bridged Showing Virtual Extension for Remote Extensions after v18 update

[jvbac]

Setup is three 3cx installs to 3 different offices all bridged.
All were on v16 and had been working fine.
We updated one office to v18 and now every extension from that office is showing the virtual extension plus the "real" ext number
This is Showing in Address book and when they call any other office across the bridge

A call from the other two offices between both v16 3cx installs still works as it should only showing the real 4 digital extension on each side

The only thing changed is the upgrade to v18 at this one location

I added a rule to accommodate the extra numbers for now, but would like to see it back to just seeing the real extension number.
Is it something with the data going from v18 to v16? Plan is to update the others to v18...but this was a smaller office to update first

Thanks in adv!

Just noticed presence is not carrying over on a v16 to v18 bridge.
(or v18 to v16)

...and just found this lol so at this point one is to assume this could be the problem

• Customers using bridges: Important that both PBXs should be V18.

That is absolutely right, as mentioned in our blog post all bridged PBXs must be running v18 and to be more precise the same version (ideally the latest) so do let us know if the issue persists after you sort this out so that we can take a closer look if needed.
