View Full Version : QuadroISDN registered in 2 different IP-PBX servers

12-16-2013, 11:59 AM
I have created 2 extensions (attendants): 00 and 11.

"00" connects to Asterisk-1 located on same private LAN (172.26.xxx.xxx)

Incoming/outgoing calls work OK (ISDN trunks 2, 3 and 4)

"11" registers OK to an Asterisk-2 outside LAN (Amazon EC2, 54.201.xxx.xxx)

Incoming calls (ISDN to Asterisk-2) work OK.

Outoing calls do not work because when my IP phones (connected to Asterisk-2) want to call through ISDN, QuadroISDN rejects invites with:

-- Executing Dial("SIP/0929xxxx-00000109", "SIP/quadroISDNamazon/65619xxxx,60") in new stack
-- Called SIP/quadroISDNamazon/65619xxxx
WARNING[1760][C-00000086]: chan_sip.c:22927 handle_response_invite: Received response: "Forbidden" from '"Jose Amazon" <sip:0929xxxx@54.201.xxx.xxx>;tag=as31270b8e'
== Everyone is busy/congested at this time (1:0/0/1)
HangupCause = 21 (Forbidden).

Quadro's firewall is disabled.

QuadroISDN is connected only through LAN port 1.

Is it possible this scenario on the QuadroISDN?

Should I switch from LAN port to WAN port?

Latest Firmware: 5.1.16 (2009)

I changed to WAN port and I get same error.
