Hello All,

i am working on Windows XP platform and analysing VoIP calls with ethereal. 
As far as i know, latest version is "ethereal-setup-0.99.0.exe(13,053,058 
16.05.2006)" and it's installed.

i have a problem with H323 VoIP call encoding in Ethereal and need urgent help.
During RRQ request, "terminalAlias" field has set with two items 
(dialedDigits:"5295672",imsi:"1234567890123456") such as;

Item 0: dialedDigits "5295672"  and decoded correctly (OK)
Item 1: mobileUIM->
        ansi-41-uim->           
        imsi: "12345678901234561#77771c##2?##5###43##....." decode failure
(NOK)

With other commercial analysers decode same hex data correctly.
(linkbit.com/support-decoder.html by selecting IP->layer4->H323 RAS)

if needed, i'll support Ethereal traces.
Is there any patch or missing library ?
Does anyone can help?

Ozgur
