CO double ring

[keyset6]

We have a 9006.3 with a couple on answering systems on analog lines. One brand won't pick up on a CO call that's transfered due to the double ring cadence. I changed SYSDA - RNGTYPE - UNANSCO from COCALL to NORM. On Rolmphones the ring cadance is now always a single ring, as if an internal call but the analog lines still give the double ring. I wonder where else, if it all, there's another setting to be changed? Didn't see anything in TIMD1.

I was having this problem with some fax machines for a while, but they all seemed to work after I set them to answer on the first ring - then any blip on the line is usually enough.

You could maybe try increasing the duration of the timers for CO1ON and CO2ON in TIMD1 to closer to 1000ms which is the normal ring. Then even if the Analog stuff still uses those timers the ring length will be longer.

I was thinking of fooling around with those, maybe that would do it. What's really weird is they said (& I believe them) that they've had the answering systems for a few years and the trouble just started. Nothing was changed as I the only one who accesses the PBX. Thanks.

That's what happened for me too. Everything was working fine and the problem just started after an upgrade, but my problem wasn't just answering machines and faxes - I had regular analog phones that were ringing funny too (the ring cycles on the phone cards (relay clicks) did not match the power cycle on the RG cards. The ring relay would be closed when the RG card was in the low power state (LED off) and just opening as it went high (LED on) - resulting in feeble little dings and half-rings. Everything was out of sync). I swapped ring generator cards (RING or HORG) and shelf power supplies and it made no difference. I was able to get the faxes to answer if I set the rings to 1. Why they came out of the box set for 4 rings I haven't a clue.

I finally solved my problem by getting pissed of and hard downing the entire switch and bringing it back up. Apparently it was just a bad load of the software that was causing the problem, and everything synced back up at power-on.

That's interesting taking the switch down/up to fix it. I tried so many things, even setting up the line as FAX, creating a phantom always forwarded to the target, member of a hunt group etc. While it did seem to change the ring cadence on internal calls I'd always get the exact same stupid CO double ring. You'd think a popular answering system like Lucent wouldn't care about the ring length. They have another brand answering system, Uniden or GE, don't recall but it answers fine.
