CLIP on analog set just shows directory number or utf8 char too?

Clip on analog is being transited mostly with ITU-T v.23 (1988 valid) search for Bell 202 modem. orhttp://www.itu.int/rec/T-REC-V.23-198811-I
Clip on PRI is by some part of ASCII (not even full ascii range !, don't even think that UTF8 will be possible ever, as i remember), see this:

Code: Select all

 logger.c: > Progress Indicator (len= 4) [ Ext: 1  Coding: CCITT (ITU) standard (0)  0: 0  Location: User (0)
logger.c: >                               Ext: 1  Progress Description: Calling equipment is non-ISDN. (3) ]
logger.c: >[b] [28 0c b1 6f 48 79 6c 4d 20 73 6f 73 65][/b]
(in Ascii: '(±Holy Moses ')
logger.c: > Display (len=12) Charset: 31 [[b] Holy Moses[/b] ]
logger.c: > [6c 0c 21 83 36 31 32 35 35 35 31 32 31 32]
logger.c: > Calling Number (len=14) [ Ext: 0  TON: National Number (2)  NPI: ISDN/Telephony Numbering Plan (E.164/E.163) (1)
logger.c: >                           Presentation: Presentation allowed of network provided number (3)  '6125551212' ]
logger.c: > [70 05 a1 34 33 32 32]
logger.c: > Called Number (len= 7) [ Ext: 1  TON: National Number (2)  NPI: ISDN/Telephony Numbering Plan (E.164/E.163) (1)  '4322' ]
But i as i see this, only chars in range of about ascii (decimal) 32-128 are transmited, so a-z, A-Z, space, underscore 1..9, 0 etc... I don't know if any norm in ITU-T whould allow for UTF-8 or even a national encoding (like a-ogonek in my country http://www.fileformat.info/info/unicode ... /index.htm)

Maybe on sip-trunk you will get full CLIP with UTF-8, on ISDN or analog, no way in this century :o .

Thank your for your complete explanation.
My analog set could not display even Directory name for internal calls. Only directory number is showed in this case.
