Good afternoon everyone :o)
I have a weird problem on our PBX - Every time we dial a specific number (01234 567890 - let’s say, for arguments sake) - The call seems to leave the PBX through our SIP provider, then come straight back to the PBX with [email protected] with the following error:
– Called SIP/VoIP Unlimited/01234567890
[2013-01-23 15:02:43] NOTICE: chan_sip.c:19556 handle_response_invite: Failed to authenticate on INVITE to ‘“our-outbound-sipID” sip:[email protected];tag=as2b941758’
– SIP/VoIP Unlimited-0000001e is circuit-busy
Any idea’s people? I haven’t made any changes to the dial-plan that I actually know of! It seems to be several random numbers that this happens on.
