I am facing this issue with my 9971 phones connected to UC520.
Whenever i am trying to dial an international number that starts with 8 as prefix i.e 800XXXXX as soon as i press 800 it starts giving me fast busy tone.
But works with all the regular 7975 and 7945 phones therfore not a problem with line seems some problem with configuration.These calls are going thru sip trunk ( if it has any issues with 9971 and sip).
voice register pool 1
id mac ACA0.16FD.584A
number 1 dn 1
username barigs password 123456
with dial-peer as:
dial-peer voice 106 voip
corlist outgoing INTERNATIONAL
description *** International Calls ***
translate-outgoing calling 3
translate-outgoing called 100
session protocol sipv2
session target ipv4:10.209.4.58
I tried applying the corlist to the voice register dn but it seems this command is not permitted here.
Any suggestions welcome. Need to resolve this urgently.
