I have HT503 connected to huawai ft3110 as pstn line. FT3110 is a “Fixed wireless terminal”.
FT3110 works fine with any phone I have attached to it (phone dials every time, rings long for incoming calls and shows caller ID).
Currently I faced two issues.
The first issue is: If I dial *00 I can hear the dial tone but the DTMF tones always dial a wrong number. But if I route some numbers to pstn (L: x… in FXS tab), then these numbers are dialed absolutely correct. The difference is that I don’t hear the dial tone. I just dial the number and ht503 somehow sends it to the pstn correctly. I tried different AC and Gain settings but I always get a wrong number response (sometimes it is wrong code). Any of my phones can dial when is attached to ft3110. Any ideas how to solve this?
btw: voip to pstn works well and dials correctly.
The second issue is even more interesting. The pstn incoming call starts ringing the phone on FXS port but after two rings the phone stops ringing. I dial it from my mobile phone and I hear that it continues to ring. In practice phone on FXS port give up after the second ring and after the caller ID is detected and shown on the phone display.
I found that the above behaviour is related to the caller ID. If I change the "FSK Caller ID minimum RX Level " to -70db the phone rings all the time but doesn’t show a caller ID. If the caller ID is shown (at default level -40dB) then the phone on FXS port stops ringing. Any ideas about it?
“Ring Timeout” is default value
“Number of Rings” is set to 30
I know It is long but I spent some time on it:)
