Caller ID display on FXO

I do have a basic h323 setup. A single phone line (w/ CLID enabled from provider) connected to my voice router on FXO port. I configured the router as follows:

Gateway

voice class h323 1

h225 timeout tcp establish 3

dial-peer voice 95 voip

description TO-CCM

destination-pattern ....

voice-class h323 1

session target ipv4:10.10.10.100

dtmf-relay h245-alphanumeric

dial-peer voice 25 pots

description TO-PSTN

destination-pattern T

port 2/0/1

!

voice-port 2/0/1

connection plar 2002

description H323 Pilot

caller-id enable

!

2002 is my own ip phone connected to the 10.10.10.100 CCM. everything is fine except caller ID. The phone line has CLID enabled, I have verified this by direct connecting a CLID capable normal phone set.

Whenever an external call comes to my IP phone it is still showing "from unknown number'. Anybody have any suggestion? what to check next ..? any troubleshooting steps..

Regards

Re: Caller ID display on FXO

Give it a try in your dial-peer to see if it helps.

dial-peer voice 95 voip

description TO-CCM

destination-pattern ....

voice-class h323 1

session target ipv4:10.10.10.100

dtmf-relay h245-alphanum

Re: Caller ID display on FXO

'no clid strip' will work only if 'clid strip' is set. IOS puts a a message for you, while i tried to configure this.

Re: Caller ID display on FXO

Depending on your telco, they might send the caller id during the first or second ring. Try changing this on the voice port and see if that helps. Here is the command

caller-id alerting ring [1|2]

Re: Caller ID display on FXO

I checked the debug:

----- ccCallInfo IE subfields -----

cisco-ani=

cisco-anitype=0

cisco-aniplan=0

cisco-anipi=0

cisco-anisi=0

Calling Number=(TON=Unknown, NPI=Unknown, Screening=Not Screened, Presentation=Allowed),

Jul 28 15:01:51.061: [2/0/3] get_fxo_caller_id:Caller ID receive failed. parseCallerIDString:no data.

We dont see any caller ID coming at voice ccapi level.

You must configure the alerting method when the Caller ID standard, specified by locale through the cptone command, is not Bellcore/Telcordia. (The one you are using is BELLCORE)

Jul 28 15:01:37.993: [2/0/3] htsp_start_caller_id_rx:BELLCORE

If you do not configure the alerting method, the default caller-id alerting ring 1 command is applied. The command that you enter is determined by the Bellcore/Telcordia or ETSI standard that your service provider uses for Caller ID.

Try upgrading to the latest IOS and give it a try with a different FXO port. I would contact the Service Provider to check the line.
