Caller-Id not updated for incoming call

Answered Question
Apr 14th, 2009

Appologies for having more questions than answers at this stage... hopefully I can pay back once we have solved a few of our issues!

I have an odd problem, I have the UC520 connected to the PSTN via a pair of analogue lines. I have enabled caller-id and was pleased to see that the calling party's number is displayed for an incomming call...

However, it appears that once a given number has called, the caller id display for all other incoming calls is the same (i.e. that initial caller).

I have tested the line and the caller id info presented by the telco is correct (i.e. always matches the caller).

Its like the first call has latched the data somewhere that then never gets updated.

Anyone got any clues or ideas?

(We are using the UK PSTN) Relevant extracts from my config are;

voice translation-rule 1111

voice translation-profile CALLER_ID_TRANSLATION_PROFILE
translate calling 1111

voice-port 0/1/0
trunk-group ALL_FXO
translation-profile outgoing CALLER_ID_TRANSLATION_PROFILE
cptone GB
connection plar opx 201
impedance complex2
  caller-id enable
caller-id alerting line-reversal

I have this problem too.

In the past - if this is an analog line from BT - we have seen you need the below CLI for caller ID to work

voice-port x/y/z

caller-id alerting dsp-preallocate

See if that helps

Perfect.Problem now resolved.

I read (in non-Cisco documentation) that the UK PSTN should use caller-id alerting line-reversal.... this must be incorrect.

The following setting does the trick (as you suggested)


caller-id alerting dsp-preallocate

Thanks for your help.
