Agree. 503 has become badly misused. On Oct 20, 2015, at 22:48, Alex Balashov wrote: ‎Thanks. And I'm guessing the best one can hope for from a SIP termination provider is an ambiguous 404, or, more likely, a 503, which seems to have become misused an opaque,

We struggled with this and eventually integrated our switch with Speedeon Data. They have a disconnected number scrubbing API. We sell it as an additional feature to customers who are interested in knowing when numbers are disconnected. On Oct 20, 2015, at 7:39 PM, Alex Balashov

Wouldn't is be cause code 1, unallocated number? http://www.dialogic.com/webhelp/img1010/10.5.2/webhelp/General_Reference/def_sip-ss7_cc.htm On Oct 20, 2015, at 21:38, Alex Balashov wrote: ‎Hello, Are there ISUP cause codes for disconnected numbers? And if so, do

I ‎would have thought 1 means that the number has no entry in a switch translation table, which is something logically distinct from disconnection. I suppose it depends on how LECs implement the state of affairs to which "disconnected" colloquially refers. ‎ -- Alex Balashov | Principal |

Re: [VoiceOps] Disconnected numbers and SIP

I would consider anything but 404 (at least as long as the terminating LEC send a cause code 1 properly) a glaring bug that I would demand a fix for until I received one, but I have different standards than most (many?) folk it seems. But I have zero tolerance for exotica on my TDM or SIP

Re: [VoiceOps] Disconnected numbers and SIP

Yeah, looked at that. I meant more from a "de facto" / what vendors actually do perspective, which, as you know, has tenuous attachment to the RFCs. :-) ‎ -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel:
