Milliwatt
Hey,
I have done the same search to no luck.
The Milliwatt app I don't think telkom will use, since it's an application used in asterisk's extensions.conf file <- and telkom will not be found using Asterisk... no, their too good for that. And the 1004hz app they will probably not share. My gf works for a telecom company and they know a telkom technician pretty well. She's going to find out for me. But until then I'm screwed as well.
Either way, back to asterisk. Adding an extension like so:
exten => 1116,1,Answer()
exten => 1116,n,Milliwatt()
When dialing 1116 now, a fairly irritating 1004hz sound will play back to you.
You will need to have either 2 asterisk machines connected via telkom lines, or know someone else who can help you out. This signal has to travel through your Zaptel in order for you to effectively alter the gain.
If you want we can help each other out and I can set this up on my side, you on your side and we dial each other. Then just have the other party transfered to this extension number and they modify their gain.
Maybe even make a reverse billing number from it ;> as I'm sure maybe ZA guys want this (or they already know of one).

Well
Seeing as you have shown me how to set it up - I will do so.
I will publish the DID number here for anyone to test off of. how do I verify tho, that my gain settings are correct before publishing this?
How can I add the extension permanently through free pbx.
I hate loosing all my extensions each time I reload freepbx.

Using an analogue line to generate the test tone is a bad idea (at least unless you've already tuned that analogue line). ISDN is perhaps a better solution.
I've set up a test tone number on 087 550 0127, however, I'm a little concerned that this may not be perfectly calibrated.
I also tried also setting up a test tone on an ISDN BRI line and then dialled both numbers from an analogue zap channel whilst running zttune. Both gave similar level indications which should indicate that the 087 number and 011 ISDN number are both producing similar levels.
While that does indicate that they should be working properly, it doesn't eliminate the possibility of them both being equally wrong...
I would welcome input from others on how this can be perfected. I'll happily make the 087 550 0127 a permanent number (courtesy of Switch Telecom) if this is of use to others, but short of the levels comparison against the ISDN BRI, I'm not sure how we test that it is accurate.

Hi,
It would be off of our PRI line, so it is at least digital.
Thanks for the number, I will set up ours today, and you can see what levels you get off that, that should give you a better idea of how correct your initial readings were?

Hi Guys,
Wanted to find out if you ever made progress around discovering a Telkom milliwat test tone.
Also, are your numbers still available?

087 550 0127 is still working. I'm now pretty certain that the levels are spot on.
Hope that helps.
(BTW, calls from Telkom to that number cost R0.88 per minute including VAT.)

If I make an outbound call towards you:
Visual Audio Levels.
--------------------
Use chan_dahdi.conf file to adjust the gains if needed.
( # = Audio Level * = Max Audio Hit )
<----------------(RX)----------------> <----------------(TX)---------------->
#######################* ^Ccntrl-c pressed48) Tx: 0 ( 1)
Rx: 4361 ( 4361) Tx: 0 ( 1)done cleaning up ... exiting.
If I make an inbound call towards me:
Visual Audio Levels.
--------------------
Use chan_dahdi.conf file to adjust the gains if needed.
( # = Audio Level * = Max Audio Hit )
<----------------(RX)----------------> <----------------(TX)---------------->
########################* ^Ccntrl-c pressed 0) Tx: 4532 ( 4563)
Rx: 0 ( 0) Tx: 4530 ( 4563)done cleaning up ... exiting.
If I make an outbound call towards a Telkom number, call-forwarded back into me:
Visual Audio Levels.
--------------------
Use chan_dahdi.conf file to adjust the gains if needed.
( # = Audio Level * = Max Audio Hit )
<----------------(RX)----------------> <----------------(TX)---------------->
#######################* ^Ccntrl-c pressed80) Tx: 0 ( 0)
Rx: 4362 ( 4380) Tx: 0 ( 0)done cleaning up ... exiting.
As you can see, when I monitor on the RX in both instances (i.e. Outbound call to you and outbound call to a Telkom number forwarded back to me), the RX is virtually identical.
It is technically not possible to monitor the TX when calling your number, since you are generating the TX and it would have to be monitored from you side. I don't know why there is a slight discrepency between TX and RX. Perhaps Telkom applies a slight negative gain, or, perhaps it is related to the Digium hardware.

Thanks a lot guys ... going to do my setup and testing now.
