[asterisk-users] ring splash
Something new to me. Recently installed a 1.4.30 box for a small office with four POTS lines in a hunt (Digium TDM410P). Had the telco put a call forward option on the main line of the hunt. They dial a feature code from their desk phones (Polycom IP450) that results in forwarding the main number to our VoIP service. This is all to let them try out our dialtone service before porting the number to us and ditching the POTS lines. So we perform some test calls and they all go through fine, and everyone is happy, BUT everytime a call comes through it ALSO causes the POTS line to ring, and a ghost call rings all the phones in the office (the desired result of an inbound call from POTS). When they answer it they get fast busy because it isn't actually a real call. I spoke to the telco this morning about it and they said oh yeah - that is a ring splash that lets the customer know that a call was forwarded. They said this was a feature of their DMS-100, it has worked that way for twenty years, and they can't turn it off. So to the question - can the TDM410P somehow tell the difference between a ring splash and an actual inbound call? I think in the meantime I will send inbound POTS calls to an auto attendant that will eventually hang up, but would love a more elegant solution ;) Cheers, j -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

The more complex answer is that first, the TDM410P doesn't actually know anything about detecting ringing, ring patterns, or anything of the like, it's essentially dumb hardware :-) The driver for the hardware detects the incoming ring voltage and debounces it before reporting it to the DAHDI core and then upstream to Asterisk; it is possible you could set the debounce timer to require that the ring last at least 500ms (or maybe even a full second) before reporting it, which would absorb these ring splashes. -- Kevin P.

Re: [asterisk-users] ring splash
The ring splash is a long standing feature of call forwarding. Of course somewhere in the Asterisk code a change could be made to extend the time required to detect a valid ring. But, how about just unplugging the pots lines from the PBX with a quick restore ability? Unplug lines at the NID, or open bridging clips or whatever applies.

Re: [asterisk-users] ring splash
Just set the POTS lines to answer after a second ring rather than after the first. Problem solved. On 5/26/2010 11:36 AM, Jeff LaCoursiere wrote: Something new to me.

Re: [asterisk-users] ring splash
Strangely enough I have used this many times with our POTS from ATT. We get ring splash, but didnt get a ghost ring into the system, just the valid ring that was redirected to the VoIP lines after forwarding. Although I think i had the Asterisk-GUI creating the dialplan on these systems, not sure if it changes anything besides the dialplan though that would cause it to seem normal during a forward of a POTS line. -- Trevor Benson dCAP, LPIC-1, CLA, Network+, MCP, CNA A1 Networks - Network Engineer DID (707)703-1041 FAX (707)703-1983 On May 26, 2010, at 9:43 AM, Cary Fitch wrote: The ring splash is a long standing feature of call forwarding.

But a quick look through the options in zapata.conf don't show any kind of option for waiting before pickup. Something that *did* look promising is distinctive ring detection. Has anyone used this ability to detect different ring styles? Presumably with a lot of trial and error I might be able to detect a ring splash from a real ring. ALternatively if someone knows how to actually make the card wait X rings or seconds before answering, that would be great. I'm coming up zero on searches. Its already set to wait for callerid, so I am a bit confused why it is picking up on a splash... seems it should wait for that second ring anyway.

The Wait statement before the answer appears to be the only way to handle this. I actually used this technique to deal with some phantom rings that were occurring at one of my branch offices. The Telco had the switch set up to periodically test the line (like every 30 minutes) and Asterisk was detecting those test pulses as a ring and answering the call, then passing it on into the operator queue before the system could detect the hang-up. The poor lady at that office nearly had a nervous breakdown before I figured out how to filter out the phantom calls with the wait command. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
