I don't have a proven answer, but here is an idea to try:

[ISDN-in]
exten=> 6201030,1,SetCallerID("${CALLERID}" <${CALLERID}>|a)
exten=> 6201030,2,Dial(${UserGroup1}&Local/${EXTEN}@ISDN-in-delayed|80|t)
exten=> 6201030,3,Voicemail2(u6201030)
exten=> 6201030,4,Hangup
exten=> 6201030,302,Voicemail2(b6201030)

[ISDN-in-delayed]
exten=> 6201030,1,Wait(20)
exten=> 6201030,2,Dial(${UserGroup2}|60|t)

Cheers
Tony
