Hi everyone.

We are currently using a MYPBX Soho with 2 analogue (PSTN) telkom lines.
Could anyone point me to where I can find the correct settings for MYPBX (SOHO) to work nicely with Telkom lines? I've played around with settings until finally I have it working, but actually i couldn't tell you which settings are making it work and which are causing more of an issue.
Currently I have had no success with incomming CALLER ID. It seems there is little to no information on this unit and South Africa phone lines.

Any help would be appreciated. I contacted yeastar and they told me to try two options (dtmf with detect on polarity switch / Bell USA with detect on ring) both do not work.

I know the following:

Caller ID
Caller ID Scheme: ETSI-FSK prior to ringing with RP
FSK Caller ID Minimum RX Level (dB): -40dB
FSK Caller ID Seizure Bits: 70
FSK Caller ID Mark Bits: 40
Hook Flash Duration (ms): 600ms
Number of Rings: 2

PSTN Disconnect Tone:
f1=400@-30,f2=400@-30,c=2500/500-2500/2500-500/2500-500/500; (Grandstream)
400@-30,400@-30;4(2.5/0.5/1) (Linksys)
Line Impedance: 220 Ohms + (820 Ohms || 115nF)
 
The above from Hummer is correct but in reality for only 2 lines i would port the Telkom numbers and go get a SIP account so you can use VoIP.
