Obi110 dial and ring time on PSTN

<< < (2/2)

ianobi:
Inbound ringing is controlled by:
Physical Interfaces > LINE Port > LINE Port > RingDelay
I wonder if the delay is caused by the OBi110. When calling your OBi PSTN number you may receive ringing tone before the ringing current is sent to the OBi device from the local exchange. You may prove this by putting a corded telephone in parallel with the OBi110 Line Port and seeing how long the delay is between the corded phone ringing and the phone attached to the OBi Phone Port ringing.

Dial time is a function of several factors:
LINE Port Digitmap - my suggested digitmap should have a zero delay for 0xxxxxxxxxx numbers.
LINE Port DialDelay - time to "seize" the local exchange equipment for the PSTN line.
LINE Port > DialDigitOnTime - DTMF tone on.
LINE Port > DialDigitOffTime - DTMF tone off.

DialDelay default is 500ms, it's probably unsafe to reduce this. I've reduced DialDigitOnTime and DialDigitOffTime to 80ms from 200 ms. So for seizing the PSTN line and sending the DTMF digits out there will be a delay of around 2.2 seconds simply to deliver the DTMF digits to the local exchange. Then the PSTN network will have a short delay to add in processing the digits and routing the call. Again dialling from a phone in parallel with the OBi110 Line Port will show how much of the delay is down to the PSTN network.

Thanks.

I got the the OBI to dial much faster now, but still having an issue with inbound calling taking too long to reach the phone.

Just a shame the features of the 202 are not in the 110 because that would have solved this by now.

Is there another way to resolve the issue?

Thanks

I don't think that is the case. Setting up physical PSTN landlines is very different from doing the same with voip.

My OBi110 has the setting:
Physical Interfaces > LINE Port > LINE Port > RingDelay: 0

It rings a corded phone almost instantly an incoming call arrives. However, normally I have a DECT base unit and phones attached to the Phone Port and this adds 2 to 3 seconds delay before ringing. Might this be the problem?

In your opinion, which feature(s) of the 202 would, if present in the 110, solve your inbound calling problem?

When you get this issue solved could you post the final results.
Thanks
