Phone format in OTRS AG mails aren't DIN conform

Dear OTRS AG team,


your corporate signature states your phone numers in this format: +49 (0) 9421 56818 0

This has the huge disadvantage, that most VoIP solutions on corporate desktops don't recognise this as a dialable phone number.

If you want to be called from a corporate device, the caller needs to manualy delete either the zero or the +49 part.

Since most corporates uses internal numbers, I would prefere your numbers in the +49 9421 56818-0 format (as in DIN 5008).


Is it possible to adjust your corporate signatures? This will make calling you so much easier.


Kind regards,
