Receiving incoming calls on Obi110
ianobi:
The purpose of RingDelay is to give the OBi time to process CallerID information from the PSTN line. If you have the CallerID function and wish to use it, then simply reduce it as low as you can and still keep CallerId working. If you do not have CallerID or do not wish to use it then set:
Physical Interfaces > LINE Port > LINE Port > RingDelay: 0

I changed the impedance to 270+(750||150 nF) and 275+etc and that seemed to improve the sound quality to an acceptable level
Getting a perfect impedance match between the OBi Line Port and the PSTN line involves trial and error, unless you are very lucky and have the perfect PSTN line and perfect house wiring and no other devices attached to the PSTN line.
The OBi assumes your line to be not perfect when dialling out, so applies DTMF tones for longer than most lines need (200ms on and 200ms off). To speed up dialling out I use the following settings with no problems on a fairly short PSTN line:
Physical Interfaces > LINE Port > LINE Port > DialDigitOnTime: 80
Physical Interfaces > LINE Port > LINE Port > DialDigitOffTime: 80
Others have reported reliable dialling using:
Physical Interfaces > LINE Port > LINE Port > DialDigitOnTime: 80
Physical Interfaces > LINE Port > LINE Port > DialDigitOffTime: 50
Going back to my original post advising you to disable all four of the PSTN Disconnect Detection methods - you may wish to try bringing back (one at a time):
DetectCPC
DetectDisconnectTone
If enabling one results in your original problem coming back, then disable it again. If the caller and callee both hang up on a call, then normally the call will disconnect with no problem. However, some equipment or some information lines may keep the line busy even if you as the caller hang up. This is why the PSTN Disconnect Detection settings are there. Again, some trial and error. If you are not getting any problems then no need to worry.

Thanks for the info, I will try experiment and let you know what happens

I have an obi110 in AU set up similar to you with mynetfone and telecube voip and the pstn connected to the line port. All calls in and out work well. All incoming calls are via pstn and all outgoing via voip (mynetfone or telecube)
In setting up I disable all sections on the Auto Provisioning Page so I have full control of the web settings. Then I like to manually enter all settings.
So if all else fails reset it to factory default and use these settings and see if it works for you.

Thanks for your input NoelB. Everything is working ok now and I am just trying to tweak things. Most of what your link shows is as I have it anyway but I will change any differences and see what happens.

Make a note of which boxes are checked. Then uncheck all four boxes that start with the word "Detect ..." If this solves the problem, then try checking any required boxes one at a time to see what works.
