Message From Unknown Number

Unanswered Question
Dec 6th, 2007

Hi,

My network scenario is a CallManager 5 connected by a bri interface with a Cisco 2811, IOS Version 12.4(9)T6, to a PBX.

When I make a call from the PBX side to the VoIP side i get the "From Unknown Number" message on the voip Phones (Cisco IP Phones 7961 or 7941 series).

I believe this is somehow worked around in the gateway, maybe by adding the command caller-id enable on the voice ports, but this does not seems to be available...

Does anyone knows if I'm right or wrong in this... and if I'm wrong how can I solve this issue?

If you need any more information, please tell me, and I will post it :)

Best Regards,

Ricardo Rolhas

I have this problem too.

Hi,

let's see first if the PBX sends the calling number.

"Debug isdn q931" and "Term mon", will tell you if it does.

Hi,

Here is the debug, for you to analyze.

It sends the nember it has dialed, but I don't see any info about it's own number.

I dialed 309 on the pbx side, this is what I get in the debug:

Dec 6 13:54:36.965: ISDN BR0/0/0 Q931: RX <- SETUP pd = 8 callref = 0x01

Bearer Capability i = 0x9090A3

Standard = CCITT

Transfer Capability = 3.1kHz Audio

Transfer Mode = Circuit

Transfer Rate = 64 kbit/s

Channel ID i = 0x89

Exclusive, B1

Progress Ind i = 0x8583 - Origination address is non-ISDN

Calling Party Number i = 0x00C3, N/A

Plan:Unknown, Type:Unknown

Called Party Number i = 0x81, '3'

Plan:ISDN, Type:Unknown

Dec 6 13:54:36.989: ISDN BR0/0/0 Q931: TX -> SETUP_ACK pd = 8 callref = 0x81

Channel ID i = 0x89

Exclusive, B1

Dec 6 13:54:37.185: ISDN BR0/0/0 Q931: RX <- INFORMATION pd = 8 callref = 0x01

Called Party Number i = 0x81, '0'

Dec 6 13:54:37.421: ISDN BR0/0/0 Q931: RX <- INFORMATION pd = 8 callref = 0x01

Dec 6 13:54:37.429: ISDN BR0/0/0 Q931: TX -> CALL_PROC pd = 8 callref = 0x81

Dec 6 13:54:37.449: ISDN BR0/0/0 Q931: TX -> ALERTING pd = 8 callref = 0x81

Progress Ind i = 0x8088 - In-band info or appropriate now available

Dec 6 13:54:42.565: ISDN BR0/0/0 Q931: RX <- DISCONNECT pd = 8 callref = 0x01

Cause i = 0x8590 - Normal call clearing

Dec 6 13:54:42.573: ISDN BR0/0/0 Q931: TX -> RELEASE pd = 8 callref = 0x81

Dec 6 13:54:42.625: ISDN BR0/0/0 Q931: RX <- RELEASE_COMP pd = 8 callref = 0x01
