[asterisk-dev] Caller ID in FXO channel

Hi All,
I have managed to narrow the problem. My driver supports FXS and FXO channel.
I register SIP client to Asterisk and whatever I dial from the SIP I dial(DAHDI/FXS).
I have analog loopback from FXS to FXS. The incoming calls in the FXO are IVR terminated (see my FXO dialplan on my previous email)
I get DIAHDI pick up FXO on the second call not on the first one.
(From time to time DAHDI actually pickup on the first call and in this case I do have callerid )
but most of the cases the pickup is on the second call and in those cases I have ${CALLERID(num) empty
Bellow I include a typical log in my FXS/FXO driver:
Driver receive from DAHDI: "FXS: DAHDI_TXSIG_START", driver sets the SLIC linefeed to "rininging" < ------------- first ring
Detect FXO ringing and diver calls dahdi_hooksig(fxo_channel, DAHDI_RXSIG_RING);
Driver receive from DAHDI: "FXS DAHDI_TXSIG_OFFHOOK", driver set the SLIC linefeed to "Forward OHT"
Driver detects the stop rining event and calls dahdi_hooksig(fxo_channel, DAHDI_RXSIG_OFFHOOK);
Driver receive "ioctl DAHDI_TONEDETECT" and returns -ENOTTY
Driver receive from DAHDI: "FXS: DAHDI_TXSIG_START", driver sets the SLIC linefeed to "rininging" < ------------- second ring
Detect FXO ringing and diver calls dahdi_hooksig(fxo_channel, DAHDI_RXSIG_RING);
Driver receive from DAHDI: "FXS DAHDI_TXSIG_OFFHOOK", driver set the SLIC linefeed to "Forward OHT"
Driver detects the stop rining event and calls dahdi_hooksig(fxo_channel, DAHDI_RXSIG_OFFHOOK);
Driver receives from DAHDI "FXO: DAHDI_TXSIG_OFFHOOK" and puts the DAA in offhook state
Driver detects that the SLIC has in offhook state and calls dahdi_hooksig(&wc.chans[0], DAHDI_RXSIG_OFFHOOK);
---- Conversation established. but caller id is empty --------
Anyone being able to point me in the right direction?
It is Asterisk 11.16.0 and dahdi: Version: 2.10.0.1
Best Regards

Subject: Fw: Caller ID in FXO channel
Hi All,
First of all happy new year to everyone!
I am developing an FXO driver to use with Asterisk.
My driver is working fine and I can receive and originate calls and I have both ways audio.
I have issue with the callerid however. I have set in can_dahdi.conf the default bell type starting after the first ring.
For testing I use FXS port which seems to send the calerid properly as it is displayed on an analog phone.
Occasionally I get the callerid (on the incoming calls for the FXO channel ) working but it is once per 20 calls.
It seems enabling Asterisk debug in the CLI makes the callerid detection a bit better as I see it working more often with CLI debug enabled.
This makes me think that I have timing or noise issue.
On the FXO RING/TIP terminals I do see (with oscilloscope) the callerID FSK signals. It I swith about 5Vpp and yes I see some noise.
Not sure how sensitive the demodulator is.
Before going into more details I want to ask the mailing list. Probably I have some simple signaling issue like getting the FXO off hook to early or too late.
I have my FXO context like
[fxo]
exten => s,1,Answer
exten => s,2, Noop(${CALLERID(num)})
exten => s,3,Background(/demo-congrats)
exten => s,4,Hangup
Bellow I include the log for reference.
Any thoughts or advices how to narrow the problem are welcome!
