Asterisk doesn't pick up my key tones


#1

I’m setting up a vanilla asterisk machine as an answering machine using a X100P card (analog lines) and can’t figure out why the demo dialpan can’t detect my keypresses to enter into extensions.

I’m strictly using the direct demo config files. I did reinstall over an old version of asterisk - but made sure to do clean makes and reinstalls

I’m running on SUSE 10

The only changes I made where to add to the zapata.conf file

context=incoming channel => 1

and to add to my zaptel.conf file

Any ideas?


#2

Where are the DTMF tones coming from? A SIP phone (locally), or through the PSTN line after zaptel/asterisk picked up a call through the PSTN line?


#3

They’re coming from the PSTN line. I’m using my cell phone to call in to test it out.

A few touchpoints come to mind

  1. zaptel driver 1.2.3 did not work for me on my X100P clone card. Incoming audio was disturbed. I went back to zaptel 1.0.10. Works fine for me with Asterisk 1.2.4

  2. rxgain might need adjustment. This is a parameter in zapata.conf for lowering or raisng audio levels (BTW, a corresponding dial for outgoing audio txgain is there as well). You can check audio levels like this:[code]# /usr/src/zaptel-1.0.10/ztmonitor 1 -v

Visual Audio Levels.

Use zapata.conf file to adjust the gains if needed.

( # = Audio Level * = Max Audio Hit )
<----------------(RX)----------------> <----------------(TX)---------------->

This is the PSTN dial tone of my installation with 1db rxgain.

  1. Check what’s happening on the console

asterisk -r

I found the outputs of Asterisk 1.2.x very useful for debugging my dialplan
