An It-Slave in the digital saltmine » it-slav.net http://www.it-slav.net/blogs Another Blog from a Geek that has no life Fri, 02 Jul 2010 07:33:08 +0000 http://wordpress.org/?v=2.9.2 en hourly 1 Phonzo SIP provider tries to block Asterisk http://www.it-slav.net/blogs/2009/12/07/phonzo-sip-provider-tries-to-block-asterisk/ http://www.it-slav.net/blogs/2009/12/07/phonzo-sip-provider-tries-to-block-asterisk/#comments Mon, 07 Dec 2009 20:17:47 +0000 peter http://www.it-slav.net/blogs/?p=1507 After the problems I have had with Bredband2, I want to test Phonzo.se as a new VoIP provider.

I registered on their homepage and after a couple of days I got a snail mail with my credentials.

I configured my FreePBX and calling in worked directly, but not outgoing. After 2 hours of troubleshooting I started to google "phonzo asterisk" and found several people that has the same experience. The reason is that Phonzo does not accepted "Asterisk PBX" as useragent and that is default in Asterisk.

 

After changing sip.conf

[general]

...

useragent=it-slav PBX

....

It worked!

 

I do not like unlogical stupidity so I sent an email to the support and the following bizare mail conversation occoured:

Me : Why do you try to block Asterisk? Changing useragent=garbage makes it work.
 
Phonzo: We do not try to block Asterisk in any way. Just change your useragent to something else, then it works.
 
Me: Why do I have to change it? It took me 2 hours to figure out.
 
Phonzo: You must change UA because our system do not accept "Asterisk PBX" as UA. This is something Phonzo always has had.
 
Me: Why did you introduce this limitation in the first place? When will you remove it?
 
Phonzo: The reason for this change is that the company evolve and new solutions has been implemented. If our customers finds it problematic that we do not accept UA to be "Asterisk PBX" we will remove it.
 
Me: The question is total opposite, you erlier claimed that is has NOT changed, instead it was introduced when Phonzo started.
Lets recap:
-You claim that UA "Asterisk PBX" is not allowed because that is something you introduced when Phonzo started, "why?" has not been answered.
-You claim that you do not block Asterisk because, if anyone asks, you tell them to change UA. No reason why this limitation was introduced at all. My conclusion is that you block Asterisk.
-You will remove it if it causes problems to your customers. I lost two hours and I find several other on internet that see this as problematic. Take it away.
 
Phonzo: It is not a problem to change UA it is very simple. Every other question has been answered.
 
Me: Now I have published this bizare conversation on my blog.
The question still remains:
Why do you not allow UA "Asterisk PBX"?
 

I will update this post when new info arrives.

After that it was flapping up and down for a couple of hours. My ISP is Bredbandsbolaget and I continusly looked at their so called maintenance site. Not a word about the disturbance. It really annoys me that there was no information what so ever, I tried to call them and gave up after 20 minutes of "thanks for your patience" in my ear. I tried to send an email and got an automated answer saying that they will come back to me in a couple of days. Yes days!!

 

I know for sure that the problems was not on my side, because a friends friend that lives in the same area had the same problem.

Using the default link structure in Wordpress gives links like: http://www.it-slav.net/blogs/?p=115 when a more logical link name is: http://www.it-slav.net/blogs/2008/11/17/op5-monitor-or-nagios-plugins-for-1-wire-temperature-measurement/

The more logical name gives date and title of the blog post instead of a cryptic number. Changing from one to another is rather simple, just change it in the wordpress settings, but there is several drawbacks:

  • Referers stop working, if someone is refering to your pages they will stop working until someone updates the link
  • Search engines will refer to the wrong page until the pages are indexed again and very likely the rank will drop
  • Wordpress internal references will stop working, so the mainpage links will stop working. This is real stupid and I do not understand why Wordpress behaves like this.

The solution is to install the plugin  "Permalinks Moved Permanently" which fixes this problem, make sure that the webserver allows rewrite.
