Re: Voip Concerns - Unblockable numbers, Second Opion Please!
I agree with exactly what you have said. I can and do treat the output of the MTA as a CO trunk. I've been using this as a solution in part since koolkid responded. I have been looking at VOIP providers that don't suppress the privacy headers or the other "Identity" information. Do you know if that service provides unlocked privacy headers?
The information I got from a Bresnan agent before, wasn't completely clear, and as far as I know, it is MGCP not VOIP. However, Asterisk 1.8 will have full MGCP support, so the point as far as I can see, is mute.
What I have a problem with, and the reason I'm venting and griping here, is the fact that Bresnan refuses to restrict calls that have malformed headers.. I pay for a service, and they don't deliver.
My Goal is not to have to run a PBX!!! I pay for a service, and I'm having to Rube Goldberg a solution, that they advertise!!
Again by this definition I'm referring that the Telephone number is not a full 10 digit number, does not have the required CID (ANI) info, and it's also annoying that the toll numbers, that have suppressed their identity as well..
Now I know that there are reasons why companies like Bresnan, would allow this, as some international and satellite calls don't provide a full SS7 route or ANI / DNIS info. (If I understand the reasoning).. However As far as I'm concerned they are full of crap, and let me explain why.
Any international or satellite route, goes thru a domestic trunking station somewhere *domestically*.. A SS7 channel *IS* generated from that point on.. a code of "International Call" and a 0xxxxxxxxx Designator could be applied with the simplest of ease..
I live in, and Bresnan provides services in the "USA". Where I live there is Enhanced 911. This means by tariff, they have to provide to law enforcement or other emergency services the number, and address of any subscriber on their network. The same is true with 98% of the United States.
This means they have information to provide to a SS7 channel "Identity". Granted, users of such a service have the ability to bock their information, but the headers on such a call are part of the tariff. "Unknown" is different than "Private/Restricted".
This is "supposed" to be part of a Tariff, and Call-blocking is supposed to prevent numbers that are blocked from ringing thru..
I wonder if they do this because they get kickbacks from these advertising companies. Or perhaps they are truly incompetent blobs of flotsam, who can't manage a telco network.
Either way, it's freaking annoying and disgusting at the same time.. I see no common sense reason why Bresnan allows this, or allows malformed headers..
I forgot this.. If the call is originated from a VOIP provider over IP, to a SS7 gateway, the session information is still retained, even if the SIP headers are forged, the Orig IP is still part of the headers..
Sorry I've rambled.. I'm still pissed..
