if you are using vicidial 1.8 or lesser and aah 2.2 or lesser for sure you will be having problems
i have a working aah 2.2+astguiclient 1.11/12 aah 2.7+astguiclient 1.11/12 here.
here are some basic tips in working with aah+vicidial
1. in astguiclient/admin.php change the context to from-internal
2. add Phase 6.2 in extensions_custom.conf
3. in macro-dialout-trunk of extensions.conf change line 15 to "exten => s,15,Dial(${OUT_${ARG1}}/${OUTNUM},55,to) ; Regular Trunk Dial"
4. add the meetme's of the scratch install in meetme_additional.conf
