Outbound calling from disa

greetings,

i am fairly new to asterisk/freepbx so excuse me for that…

i have several trunks setup

Sipgate (inbound/out)
Gradwell (inbound)
Zen Voice (out)

with several numbers

i have an IVR menu on an external ddi with 2 options 1 for voicemail access and 2 for the DISA

so i press 2 and enter my pin number… i then dial 9 follolwed by the full phone number and get “all circuits are busy now” but if i dial the same IVR internally the call connects fine

the same occures no matter which outbound trunk i use

any ideas?

Anyone?
