OBi110 delay on inbound pstn ringing phone

<< < (2/2)

coolclay:
I have been having the same issue, my phone rings 3 times but when I answer, people say they were about to hang up so I ask how many rings and they say 7 or 8 so that is a 4 ring delay at least

a8ree:
Having the same issue....Any solution found?

a8ree,

The delay is down to Line Port > Ring Delay. The default is 4000 (4 seconds), this suits North American Caller ID which arrives between the first and second ringing cycles.

I know that you are in the UK using British Telecom for PSTN. The first change you should make is to:
Line Port > CallerIDDetectMethod - set to FSK(V.23)

Then experiment with Line Port > Ring Delay. I use 2000 (2 seconds), but I don't use British Telecom, so you may get that down further. If you don't care about CallerID you can set it to 0. However, I would suggest that CallerID is useful, particularly for dealing with nuisance calls!

Hi Ian

I have done as you suggested however it hasn't made any difference. When I call home from my mobile, I hear 5 rings on the mobile before the house phone starts ringing. There are only 2 more rings before it goes to voicemail.

The phone service is Virgin Media if that has any bearing?

ianobi:
I believe that Virgin Media has a whole mix of different exchanges with different CallerID methods due to their taking over of other companies.

The delay caused by the OBi should still only be a function of Line Port > RingDelay. Line Port > CallerIDDetectMethod will only affect whether or not you receive CallerID.

Testing is not as easy as it seems, you can get ring tone from your mobile before ringing current is sent to the OBi110 via PSTN. It might be worth putting a corded phone in parallel with the OBi110 Line Port so you can hear ringing coming in and measure the delay before the OBi110 sends ringing to the phones connected to the Phone Port.
