Hi,
I have been trying to find solution to this problem by googleing and
experimenting but without success so you are my last chance.
I have asterisk 1.8.11 installation on Debian squeeze with HFC-S PCI
ISDN interface cards (dahdi channel, zaphfc kernel driver) , Huawei USB
3G stick, Siemens Gigaset SIP phones and IAX PC soft phone.
The problem is that when I receive call through ISDN interface and pick
up (SIP or IAX) phone, line immediately gets disconnected.
This is what I get with pri debug on :
PRI Span: 1 > Progress Indicator (len= 4) [ Ext: 1 Coding: CCITT (ITU)
standard (0) 0: 0 Location: Private network serving the local user (1)
PRI Span: 1 > Ext: 1 Progress
Description: Called equipment is non-ISDN. (2) ]
PRI Span: 1
PRI Span: 1 < Protocol Discriminator: Q.931 (8) len=4
PRI Span: 1 < TEI=90 Call Ref: len= 1 (reference 21/0x15) (Sent from
originator)
PRI Span: 1 < Message Type: CONNECT ACKNOWLEDGE (15)
PRI Span: 1 Received message for call 0x89a4e68 on link 0x88a4238
TEI/SAPI 90/0
PRI Span: 1 q931.c:8484 post_handle_q931_message: Call 21 enters state
10 (Active). Hold state: Idle
PRI Span: 1
PRI Span: 1 < Protocol Discriminator: Q.931 (8) len=12
PRI Span: 1 < TEI=90 Call Ref: len= 1 (reference 21/0x15) (Sent from
originator)
PRI Span: 1 < Message Type: DISCONNECT (69)
PRI Span: 1 < [08 02 81 90]
PRI Span: 1 < Cause (len= 4) [ Ext: 1 Coding: CCITT (ITU) standard (0)
Spare: 0 Location: Private network serving the
local user (1)
PRI Span: 1 < Ext: 1 Cause: Normal Clearing (16),
class = Normal Event (1) ]
So, after getting CONNECT ACKNOWLEDGE there is an immediate DISCONNECT
received from telco.
This happens always if dialed extension is
-- SIP
exten => ${MSN1},1,Dial(SIP/phone1)
or IAX
exten => ${MSN1},1,Dial(IAX2/phone2)
or multiple extensions
exten => ${MSN1},1,Dial(SIP/phone1&Dongle/dongle0/phone3)
but not if it is chan_dongle alone
exten => ${MSN1},1,Dial(Dongle/dongle0/phone3)
Maybe it is worth mentioning that this problem started after switching
telco. First one used simple NT device connected to the line and second
one uses Patton IAD connected to the router.
Can you help me to find a solution to this problem?
Thanks in advance.
Best regards,
Ivo.
