I have two SPA 3K's which I am using for inbound PSTN lines (among other things) with Asterisk.

They are connected to two USA purchaced GE 900mhz wireless handsets with CID.

When I connect the phones directly to PSTN without the Sipura's in the middle caller ID passes fine, but when I add in the Sipura's I get no caller id.

What are the settings that can be used to "tweak caller id"?

I should note that I am in Taiwan, but by all I can determine, Taiwan's caller ID implementation is the same as the USA (all phone related equipment I purchase in the USA works here without problem).

All help much appreciated.

Take a look at Regional tab, Miscellaneous section, Caller ID Method field. Make sure Bellcore (N: Amer/China) is selected.

It is. Any other settings that affect Caller ID?

What is possible (which is also the case in Australia) is that the timing of sending the caller ID is different. The technique maybe the same, but in America I think it starts 500ms after the first ring, and in Australia 330ms. So maybe the Caller ID is sent too late in Taiwan, so the Sipura thinks there isn't coming anything, so it won't read it to transfer it again to your phone. And your other hardware may not be that sensitive.

EDIT:

Taiwan follows ETSI in permitting DTMF and FSK signals.

That seems to me like Taiwan uses ETSI FSK (or DTMF), then? :S

Hi

I have the same problem, No CID on my sipura 3K even I have the CID service active with My PSTN Company, I have firmware 2.0.13(GWg), and also I have tried all Caller ID Method on Miscellaneous option.

Any suggestion?

Upgrade your sipura to the latest version here http://www.sipura.com/support/index.htm

What behavior do you observe when your SPA3000's Line 1 is receiving a call from your Asterisk? Does your phone display the Caller ID? When you receive a PSTN call there are two agents working in tandem to deliver the Caller ID to your phone, the FXO receiving the Caller ID from the phone company and the FXS regenerating the Caller ID to send it to your phone.

In order to solve your problem you need to figure out whether the problem is in the SPA3000 failing to recognize the Caller ID from the phone company (look at your Info page when a call is in progress) or in the SPA-3000 not generating the Caller ID in a form that your phone can recognize.

I have upgraded to 3.1.5(GWb) with not good results

mberlant:

I'm not using Asterisk, my topology is as follow:

PSTN ==> FXO(SPA-3K) ==> Inernet (PSTN-To-VoIP Gateway Enable)

Everything works fine the only problem is when I receive a Call from PSTN the FXO port never detects the CID on the Information Page; I would like to use the "PSTN Access List" but I can

gar, what country are you in? You may be connected to a telephone system that does not generate one of the Caller ID techniques that Sipura is able to decode. Also, if you are in a country that uses the US standard you may be picking up the phone before the phone company has a chance to send you the Caller ID, just before the second ring.
