A trick I learned when dealing with Turkish Telekom and CLI problems etc.. on FXO lines.

When dealing with Analog lines try to find out maker and model of the Central PBX you are connected to, then search about tha model on the internet, this might give you better technical knowledge (at least what is supported and what is not).

Good luck,
Kerem

Hi,

I think if you add some external module to capture the CLI, it wont help you
because CLI is not detected by Freeeswitch.  saying this bacause I am from
PBX line & have good experience of the said problem.

I would like to suggest to check the CLI type. It may be in FSK mode.
Eaelier I had used Grandstream FXO gateways to detect the FSK CLI. Can'nt
say about DTMF. You can confirm with grandstream people.

Having said this, another check point is - Check the CLI type whether it is
before ring or between ring. This is important if your CLI is in dtmf. If it
is so, you may have to give some time to detect the CLI. We call it CLIP
timer.

At last, someone mentioned the CLI relation with polarity reversal. i do not
think there is any relation between CLI & polarity reversal.

Feel free to discuss further.

Sharad

Hi,

I am the person whose thread you mentioned. I've also had somebody
contact me off the list regarding this. What I did in my case was jut
get some sort of dtmf converter. It costs Rs 200 and is Made in China.
You plug in your FXO line in it and take another wire from it to your
sangoma card. Caller ID is detected then. The only labeling it has on
it is NetSonic. Somebody who contacted me tried to find it online but
wasn't able to I think. I was referred to a shop here by the guy who I
buy my Sangoma cards from.


Muhammad Shahzad is right about polarity reversal, I confirmed this
with the telco (Airtel). I do have hardware to test this or give
access to somebody who wants to test a fix. But I just moved to a new
place and dont have anything set up right now. It'll take a week
before I have servers set up.

Regards
guru
