I have a strange problem.
I’m using the same dialplan to call 1800-number:
[toll-free]
;second “7″ audiocodes strips
exten => _71800XXXXXXX,1,Dial(SIP/7${EXTEN:1}@pstn-5665,60,tr)
When I call this number (through pstn-5665) 18005000347 the phone always rings busy.
When I call any other 1800-number the calls goes through.
When I call the same phone number 18005000347 through a different line the calls goes through every time.
Here is call (busy) trace to that 18005000347 with sip debug ON:
Can anybody decipher why I’m getting busy signal to that particular 1800-number but not others?
