Hello,
I am very new with IP Telephony.
We are having an odd issue with calls not coming through from a specific area code. Any incoming call from any other area code works fine. Below is the debug isdn q931 output from the problem area code...
Feb 7 20:28:18.804: ISDN Se0/0/0:23 Q931: RX <- SETUP pd = 8 callref = 0x4832
Bearer Capability i = 0x9090A2
Standard = CCITT
Transfer Capability = 3.1kHz Audio
Transfer Mode = Circuit
Transfer Rate = 64 kbit/s
Channel ID i = 0xA18381
Preferred, Channel 1
Progress Ind i = 0x8283 - Origination address is non-ISDN
Calling Party Number i = 0x2183, '312544----'
Plan:ISDN, Type:National
Called Party Number i = 0xA1, '283----'
Plan:ISDN, Type:National
Feb 7 20:28:18.808: ISDN Se0/0/0:23 Q931: Received SETUP callref = 0xC832 callID = 0x6630 switch = primary-ni interface = User
Feb 7 20:28:18.828: ISDN Se0/0/0:23 Q931: TX -> CALL_PROC pd = 8 callref = 0xC832
Channel ID i = 0xA98381
Exclusive, Channel 1
Feb 7 20:28:18.828: ISDN Se0/0/0:23 Q931: TX -> CONNECT pd = 8 callref = 0xC832
Feb 7 20:28:18.896: ISDN Se0/0/0:23 Q931: RX <- CONNECT_ACK pd = 8 callref = 0x4832
Feb 7 20:28:18.896: %ISDN-6-CONNECT: Interface Serial0/0/0:0 is now connected to 3125449765 N/A
Feb 7 20:28:53.361: ISDN Se0/0/0:23 Q931: RX <- DISCONNECT pd = 8 callref = 0x4832
Cause i = 0x8490 - Normal call clearing
Feb 7 20:28:53.365: %ISDN-6-DISCONNECT: Interface Serial0/0/0:0 disconnected from 3125449765 , call lasted 34 seconds
Feb 7 20:28:53.365: ISDN Se0/0/0:23 Q931: TX -> RELEASE pd = 8 callref = 0xC832
Feb 7 20:28:53.385: ISDN Se0/0/0:23 Q931: RX <- RELEASE_COMP pd = 8 callref = 0x4832
The call appears to be missing the alearting message. Any ideas?
Thank you in advance
