[Asterisk-Users] Problem with character encoding in SIP channel (ISO vs. UTF-8)

[Martin Blatter]

Hi

I recently noticed that asterisk passes Caller IDs and SendText messages
containing sepcial characters (such as the german umlaut characters äöü)
with ISO-8859-1 encoding to the SIP phone. Hence user names and text
strings like "Müller" are not correctly displayed on the receiving phone.

According to RFC 3261 SIP uses UTF-8 encoding. Shouldn't asterisk
convert these characters from ISO-8859-1 to UTF-8 before passing
them to SIP devices?

Best regards
martin
