Just had a problem with an incoming call. It was from a standard format UK number (0207) that you cannot phone (its outgoing call only)
The number was passed through the Obi, and a ring request issued, but there was no ring, and the Obi seemed to hang up straight away:
11:39:10 From LI1() Fork to:
PH1
PH2
11:39:10 Ringing (PH1)
11:39:10 Ringing (PH2)
11:39:10 Call Ended
The same number tried again and this time the OBi rang the phones OK
Just wondered if there was a bug in the new 3 ms setting?
Kind regards
Mike
Always the possibility that there is an issue with the setting, after all they have modified it.

Hmm on the SPA, PSTN Disconnect I had:
Detect PSTN Long Silence: no
Disconnect Tone - 400@-30,400@-30; 2(*/0/1+2)
And this page is similar: http://www.aoakley.com/articles/2008-01-08.php
With:
Detect PSTN Long Silence: no
Disconnect Tone - 400@-30,400@-30; 2(3/0/1+2)
I seem to remember that the simpler disconnect tone you have, though it accord with a UK standard, was found not to be what is actually used in the UK
But this may be memory failure.... Maybe it's a format difference.
Kind regards
Mike
This was all tested and discussed a long time ago between myself and Obihai.
If my memory serves me correct, Obihai devices didn't support some of the characters that were used in Linksys/Cisco syntax. Such as '*', of course this may have changed as new firmware has been released since then... I said may
However, with no change logs there is no way to know.

Ring control
Also from: http://www.aoakley.com/articles/2008-01-08.php
Ring Validation Time: 256ms
Ring Indication Delay: 512ms
Ring Timeout: 640ms
On the SPA I had ring indication delay = 0 like you, and ring timeout of 128ms like you, but validation time of 256ms like aoakley
I am not sure how ring indication delay and ring delay (latter present only on the Obi) relate.
EDIT: I misread this sorry...
"On the SPA I had ring indication delay = 0 like you, and ring timeout of 128ms like you, but validation time of 256ms like aoakley"
What you say is indeed correct, those are the values used on the OBi?
I have not read this thread myself, might be of some help:

Caller id
Caller id method and detect method, you have FSK
I and http://www.aoakley.com/articles/2008-01-08.php have one setting on the SPA:
Caller id method = ETSI FSK with PR(UK)
BUT Obi does not seem to have that option.
Again already discussed, OBihai stated that FSK(V.23) works the same way.
"British Telecom FSK
British Telecom (BT) in the United Kingdom developed their own standard, which wakes up the display with a line reversal, then sends the data as CCITT v.23 modem tones in a format similar to MDMF. It is used by BT, wireless networks like the late Ionica, and some cable companies. Details are to be found in BT Supplier Information Notes (SINs) 227 and 242; another useful document is Designing Caller Identification Delivery Using XR-2211 for BT from the EXAR website."

Tones
There are detailed differences, between your Obi settings and mine and aoakley's but I guess these don't have functional impact.
What you have to remember is that not all devices take the same syntax strings, offer the same settings or name their parameters the same. If all manufacturers used the same dialplan, tones and ringtone syntax I wouldn't have grey hairs!
