Outgoing call by main ... not SIP

[mantod]

Hi, it's my first post and my first avaya's experience
In my company, i've an avaya ip office 500
In IPO, incoming a phisical ISDN line and i've setting 3 voip number in a SIP trunk (line 20)

With 0N we make call by main line (ISDN)
I setting a new function 8N -> compose -> N"@voip.eutelia.it" -> 50: Main
In ARS I make function code 8N -> NsXXXXXX"@voip.eutelia.it" -> compose -> 20
XXX is the voip number

I tested concurrently:
1) first ougoing call using 8XXXXXXX
2) a second ougoing call using 8XXXXXXX
3) a third outgoing call using 0XXXXXXXX
but when i make third call, line is busy

Anyone can help me?
I would use for outoging call voip line to have free main line

thanks

hi, you cant use ISDN line with a SIP line.

if you still want to use GO to system---telephony----UNCHECK (Restrict Network Interconnect)
