Hello all i have set up my astyerisk@home system using also a zaptel
telephony card for my landline, when i call in i can hear my music on
hold fine and extensions ring but i cannot dialout either using ZAP
(my landline) or SIP

the settings are

i created 2 trunks with sip and ZAP and 2 outbound routings with dial
patterns 99|. for zap (landline) and 88|. to select the sip provider.
Both return busy when i dial out like 99+a number or 88+a number

why does this happen ?

cheers
