IP PHONE not getting caller-id (unknown number)

[AsepRizkiKhoeisman1481]

Hi everyone,

I have a problem with incoming call on our cucm systems. when we received incoming call from external number phone (*such as mobile phone number), the ip phone screen is not get the caller-id or an unknown number appears on ip phone screen.

telco confirmed that they already sent the caller-id on their side and when they try some test with phone analog, the caller-id is appear as mobile phone normally. 

we tried check the log on our VG on port Voice-port and the log is shown that the caller-id received but the ip phone still unknown number.

the route map protocol is like this :

PSTN - FO - MODEM ZTE - FXO - VG - MGCP - SIP PHONE

here is the log on our VG voice-port 0/1/0

Jan 14 02:39:21.553: [0/1/0] get_fxo_caller_id:Caller ID received. Message type=4 length=25 checksum=6F

Please check these three things in your FXO port configuration,

1) CPTONE set to your exact country code

2) "Caller ID enabled"  command configured in that port

3) Caller id ring alert is greater than or equal to your Telco configured rings.

Hi Aswin,

here is the configuration of the voice-port

voice-port 0/1/0
supervisory disconnect dualtone mid-call
supervisory custom-cptone fxo
no battery-reversal
timeouts call-disconnect 3
timeouts wait-release 3
timing hookflash-out 50
timing guard-out 1000
caller-id enable

following your suggest

1) CPTONE set to your exact country code

- i tried to changed the cptone same as our country indonesia. so, i changed the cptone to cptone id. but it still not solved.

2) "Caller ID enabled"  command configured in that port

-"caller ID enabled" already

3) Caller id ring alert is greater than or equal to your Telco configured rings.

- i tried changing the ring signal from 1 to 4 sequential, it also nothing happen.

anybody have an idea to fix this problem?

[Aswin S]

Then please try "Caller ID alerting line-reversal" concept in your FXO port to trigger the reading of caller id when it receives.

i didn't find that command on the router vg. it's a hidden command? or it's not available on current ios version 16.08.01 ?

here i attached the image that i can't find command

"caller-id alerting line-traversal"

[Aswin S]

Yes please try "caller-id alerting dsp-pre-alloc" as this is FXO line.
