Dear Daniel

Many thanks for that fast and detailed answer!

That's really strange, I can reproduce this umlaut error with firmware 38.70.1.33 and 38.70.0.185. For example, Letter ü is displayed as eA, letter ä is displayed eO. Interestingly, internal calls with ä ö ü are displayed correctly. Also entries in the local phone directory are displayed correctly.

I use FreePBX 5.211.65-21 with CID Superfecta 2.11.16. The source of the CID's is Swiss phone book provider local.ch.

Well, it seems that the problem could be rooted in the CID Superfecta module. Will check this first. Thanks for your efforts.
