Is PSTN sending caller-ID information? Please run "debug voice ccapi inout" aso that we can check if we are receving calling party number.

If u plug in an analog phone with callerID display to the telco/pbx
line (line that's plugged into router's FXO port) and place
a call from outside, do u see callerID display ?
Also, is it the caller ID name or number that you are not seeing?
Please capture "debug vpm signal" and attach your config
for review if you this needs to be investigated further.

FYI, if you have CLID enabled on the FXO, and the CP tone is configured properly, and CLID doesn't work, but it works with an analog handset, then get:
> debug voip ccapi inout
> debug voip hpi all
> debug vpm sig
> debug vpm dsp
Collected via:
Router(config)# service sequence
Router(config)# service timestamps debug datetime msec
Router(config)# logging buffered 10000000 7
Router(config)# no logging con
Router(config)# no logging mon
Router(config)# voice iec syslog
Router# term len 0
Router# sh logg
But before you do that, you may want to try changing the 'caller-id alerting ring X' setting in case the provider is sending the CLID after a non standard amount of rings for that country. That should be evident when you do the analog phone test, though.

Start at the point where the PSTN calls first reach your network domain which would be a debug on the gateway. Do a "debug isdn q931" to see if the calling party number presented or restricted there to start. If it is then the provider is blocking it, otherwise check the Device > Gateway > Port settings on call manager.

Hi,
Is this a PRI or a FXO? And how is gateway configured? H323 or MGCP gateway
11-08-2010 03:18 AM
Its Normal FXO port .
the gateway configured as H.323 gateway .
11-08-2010 03:23 AM
Ok. So is "caller-id enable" command given under the voice-port of FXO?
11-08-2010 04:31 AM
yes , its enabled .
this is the configuration under fxo port :
voice-port 0/3/1
trunk-group XXXXXXX
compand-type a-law
cptone BR
timeouts ringing infinity
connection plar opx XXX
caller-id enable
caller-id alerting dsp-pre-allocate

Actually the correct debug to run in these cases is "debug vooce vpm signal".
However, often Cisco is very flaky in detecting caller-id, moreover Brazil uses a totally different standard from other countries, so either the Cisco TAC has a way to get it working, or one is out of luck.
