That's a good point. I just checked and the vanity DID I really want
is not available in any area code. So either I'll come up with
something else or just stick with my acceptable but not optimal vanity
toll free. Thanks!

Re: [asterisk-biz] vanity toll free

I don't really see the point. "Toll-free" is becoming less and less
relevant as mobile calls don't make a local/LD distinction and most VoIP
lines don't either.

[asterisk-biz] vanity toll free

What's the best way to get a good vanity toll free number? Or is it
pointless? All of the good ones seem to be taken by phone sex
operators or something. It's similar to the top level domain name
thing: They are cheap to own so people squat them and use up all the
namespace.

I've googled and found various places which claim they can get me
vanity toll free numbers and they all feel rather sleezy. Most seem to
lead you on to think the number you want is available and then end up
pitching you something like 877-161-216MYCOMPANY.

I've done business with one toll-free broker and have mixed feelings
about the result.

[asterisk-biz] International DID Needed (Morocco)

Hello,
I am setting up an Asterisk PBX and need to find a company that can provide me a Moroccan DID phone number.  I will be setting up a SIP trunk and using that phone number for incoming calls to their office.  Thanks.

Re: [asterisk-biz] Fraud alert

What about tying this to a program called denyhosts? It works great for
banning systems that attempt connections via ssh. I doubt that it'd be
terribly hard to integrate so that sip and iax2 could be blocked also.
It also has the ability to share block lists among systems.

[asterisk-biz] Audio issues: consulting required

We run a small number of Asterisk servers in a data centre and are noticing glitches in the audio. These glitches are consistent (i.e. the same type of problem) and happen frequently at random intervals. The audio problem takes the form of a dropout in the audio that is audible to the customer. We need some help in diagnosing the cause of these audio issues which we believe are network related (a recording of the milliwatt application sounds fine). These servers all run Asterisk 1.2 and use SIP only (no ISDN, IAX etc).

 

If you are able to provide some consulting skills in this area please contact me off list and advise relevant experience, references, rate, availability and approach.

 

Thanks

This sounds very much like the framework I discussed at the last
astridevcon in September. I've had no time to work on it, but it
sounds like you're already making progress.

http://astridevcon.pbwiki.com/Network-Security-Framework

Would you be interested in making your work more integral to Asterisk,
so that it can be a generic security policy model for all channel
methods, starting with SIP? Or is the scrape-from-logfile method
sufficient for your needs?
