I just bought a mediatrix 1204 as a home gateway. I have it hooked up to a raspberry pbx and everything is working fine on the SIP end. It is connected to a POTS port supporting BT infinity. I am struggling with the following however:
CLID not being passed from PSTN to SIP extension
Call hangup not working from PSTN to SIP extension
Dial tone not detected by mediatrix for outbound calling from SIP extension to PSTN
I set the country parameter to uk-etsi-fsk but not sure what I am doing in terms of matching the tones etc. I set DTMF to inband (also tried info and 2833) but none of the options fixed any of the problems.
Can anyone advise?
