we experienced an audio problem during the call connection.Caller can hear nothing after dialing a destination number. In fact call is connected.(it shows “normal clearing”in call log).
Anybody has the familiar experience?Or pls give us some clues.
Thank you.19th March 2002 at 03:43 #21328AushmanGuest
Please check your IOS version .Try to compair with your other end or upgrade to 12.2 Xbi ..
Also If you have no ringing problem you need to insert some commands in your far end gateway.20th March 2002 at 00:17 #21329izumiGuest
hello Aushman ,
Thank you for your help.
the originate gateway is with
IOS Version 12.1(3a)T1,we can not upgrade it to higher ver, since it is limited by the size of flash memory(8MB).
We made a call successfully on originate cisco (using csim command),it can ring the destination(mobile phone). But when we try from phone–pstn-
pbx-originate cisco–IP,it failed to ring the destination.
We have tried to extend wait_release time on both side(cisco) but still nothing
changed. IOS Upgrading is the only solution ?20th March 2002 at 03:26 #21330AushmanGuest

Hi Mr. Aushman,
Have you resolved the problem of Mr. Izumi? We too have the same problem. Please help!7th February 2005 at 13:57 #21332Teodor GeorgievGuest
Check if it is not a codec mismatch problem. Run a debug (debug cch323 h225) and look at the output.
Also, check for any access-lists on the way that might block the UDP (RTP).8th February 2005 at 06:19 #21333joemaiGuest
Thank you sir for attending our problem.
Upon running a debug, we monitored that we are not getting any TX Answer signal. Also when we show call active voice the output looks like this:
22A4 : 5565690hs.1 +-1 pid:0 Answer connected
dur 00:00:00 tx:137/4393 rx:0/0

You will notice that the ouput codec is gsmfr, but we set this as g729r8.8th February 2005 at 07:38 #21334Teodor GeorgievGuest
See that you are not getting any voice from the other side:
Do you hear a ringback ?
If not, have you configured the progress indicator items at your dialpeers ?8th February 2005 at 07:53 #21335joemaiGuest
Sir there was an error in our log:
%SIGSM-1-NO_TEMPLATE_ERR: No static template found for slo
t 3 port 3 with parameters provided
What is the cause of this error? We’ve searched the net and it says Signaling service manager. We also can’t hear a ringback tone. Maybe because of signaling.
