Hello,
It's my time.....
I've a 4FSX-DID module, with dial-perr voice associated like this:
dial-peer voice 200 pots
description analog phone
destination-pattern 888
port 0/2/0
Connected to port 0/2/0, an analog phone.
If I call from inside, the analog phone rings correctly, and the caller hear that the destination phone is ringing correctly.
But, if I call that phone from outside, the analog phone rings correctly but the caller doesn't hear the well known ringing tone...
Sorry for my basic questions.
Thanks a lot.
Marco.

Marco,
Where from are you calling the fxs ? An ephone? a BRI? When you call from another phone in the same wic, do you hear ringtone?
03-28-2007 03:20 PM
I'm calling the fxs from an E1: in this case I hear nothing.
With internal phones I can hear ring tone correctly.
Tomorrow I'll test the call from other analog phones connected to the FXS module.
Thanks.

On debug isdn q931, you will see if the router is sending alerting; that should make the caller hear ringback. If it does but no ringback, one check with the telco should be done, but in case they can't help, there are workarounds.

Hello,
I've done some tests.
This is an External call that calls the fxo port:

###############################
it seems that the alerting is missing...
I've specified in the E1 (where the external calls arrive) "sending-alert", but nothig changed:
interface Serial0/0/0:15
no ip address
encapsulation hdlc
isdn switch-type primary-net5
isdn overlap-receiving T302 2000
isdn incoming-voice voice
isdn send-alerting
isdn sending-complete
isdn outgoing display-ie
no cdp enable
!
In externals calls to Cisco phones or calls between FXS the ring tone is regularly instead.
Any idea?
Thanks a lot.

Hi Marco,
That is strange, config is correct but alerting is not sent. Which IOS is this? E.g., on an 12.4(4)XJ1 I have alerting correctly sent even if I didn't configure "isdn send-alerting":

Something you can try, but probably will not help, can you try to add a dollar sign "$" at the end of destination-pattern for the FXS ports ?

Hello,
Version 12.4(11)XJ
(c2800nm-spservicesk9-mz.124-11.XJ.bin)
Adding $ sign doesn't resolve the situation.
Can I ask you if it's normal this output?
voip#sh dspfarm
DSPFARM Configuration Information:
Admin State: DOWN, Oper Status: DOWN - Cause code: ADMIN_STATE_DOWN

The other calls are working regularly...
Thanks.

I would go ahead and upgrade to XJ1 that is available on the ftp.cisco.com when logged with your CCO username and password.
I have the same installation/configuration and alerting is sent correctly for the FXS extensions. Only, I did not define any timer for "isdn overlap-receive".
The dspfarm show down because you haven't configured anything, this is normal.

Hello,
Thanks always for your precious advices.
I don't know how I have found this, but the command:
voice call send-alert
resolved my problem :)
" To enable the terminating gateway to send an alert message instead of a progress message after it receives a call setup message, use the voice call send-alert command in global configuration mode"
Marco.

This is good news Marco.
In fact the "isdn send-alerting" it an older command that may apply to data calls only.
The correct behavior by the router would be to send first call-progress to ack the setup, and then alerting when the destination is actually ringing.
Perhaps some bug in XJ(no 1) or an unseen configuration twist is causing the above to not happen in your installation.
Anyway as anyone that can fix his own problems your post got rated by me for that.
