CPC and HT-286

**voxabox** · 09-21-2008 07:58 AM

I happened to be home yesterday when someone called.
I let the answering machine handle it. The caller hung up; however,
I ended up with an annoying "off hook/reoder" pulsing Klaxon tone recorded on my machine

updated:
I thought the annoying "off hook/reoder" tone was recorded only when the callers hung up without leaving a message. It got recorded when the callers left a message as well - at the end of the recorded message

It seemed that the HT-286 was "too slow" in detecting that the calling party has disconnected.

I experienced the same issue while I was with another VOIP provider. Fortunately, I was able to fixed it by tweaking the "CPC delay" and the "CPC duration" on the linksys/sipura ATA.

Looking through the HT-286 documentation, I did not see any provision for CPC.
The "Onhook Threshold" seems to be the closest thing.

updated:
further reading tells me that I was wrong about "Onhook Threshold":
The "Onhook Threshold" is for the hook flash/call waiting purposes!

Assuming that the HT-286 does not allow any CPC tweaking, is there anything can be done with the SIP server?

Yeah, I know, I'm olde schooled, but I still like to use the answering machine
(so that I can screen calls)

As an aside, I am hoping one day the ATA will do the message processing with a screening option. If no answer, besides recording the message, the message and envelope could get forwarded to designated email destination(s). Old school/New school at their best

I envision this ATA with a digital answering machine buttons built in, and phone key sequences, so you don't need to be at it to control it.

Just came home to find several annoying reorder tone "messages" on the answering machine

Apparently, the HT-502 (Program-- 1.0.1.8 Bootloader-- 1.0.0.9 Core-- 1.0.0.23 Base-- 1.0.0.6) still exhibits the same annoying behaviour; however it seems to happen less frequently (than the HT-286);
