Problem Summary
Shared line 7004 members have a button called 'MAPS 5' assigned to button 2 on handsets.
For no apparent reason and after no identified changes to the CME (2851), when users (members of 7004 shared line) are on a call on their primary line, if a call comes in on the shared number (7004) and is answered, all calls on the users (shared line 7004 members) primary lines are cut off (dead silence).
Suspicions
I suspect there is a but in the software bug in IOS release 12.4(20)T4 which is the cause of this, but before I sugest to the client an upgrade I just wanted to get anybodys thoughts on the matter.
Has anyone had any experince with problems similar to this?
Below are exerts from the config and I have attached the full config as well.
Thank you.
