Mobicents and Yate (Yet Another Telephony Engine) – a powerful synergy

After spending some time working with Asterisk and Yate I started to prefer the latter. Thus since most of my project is based on Mobicents and JAIN SLEE I started to think about integrating both environment. Few days later I had an initial version of Yate Resource Adapter for Mobicents ready.

Basically it works as Yate module – it connects via Yate External API and acts as any of modules. For the moment it does not process any media, but since Mobicents does not process them either I think this is ok.

The main features of synergy of Yate and Mobicents are:

  • possibility of distribution of signalling processing
  • failover – since Mobicents support fail-over and clustering the failures can be handled appropriately by the application
  • service creation in Java – the services are written as Java SBBs and deployed on Mobicents application server
  • Yate handles many signalling types like ISUP, MAP, CAMEL, SIP, H.323, IAX – which thanks to RA are available for Mobicents
  • Yate provides a lot of funtionalities out of the box which can become a part of JAIN SLEE service

The RA works stable and I will start working on a new service based on both Mobicents and Yate – e.g. Callback.

If you are interested in getting more information on Yate and Mobicents integration please let me know.

If anyone has a problems with stability of LV5HD Hybrid tuner like BSOD, freezing etc, please follow the guide:

It seems that the generic driver is too generic and it is not handling LV5HD correctly, thus it is required to install a driver provided by manufacturer instead.

Clutches installed in 1.8 TSI engines

After a short investigation it looks like:

  • Dual-mass flywheel is attached to the shaft with 8 screws - which is a common feature of all TSI engines,both 1.8 and 2.0 (CCZ, CAW, BZB, BYT, CDA)
  • Clutch (disc, dual-mass flywheel, pressure) for 1.8 BYT / BZB / CDA has a diameter 230 mm when combined with 02M  family transmission like JVX / KVT / MDP / MUF / MUE / NMY – so in case of FWD applications
  • There are rumors that 1.8 TSI when bundled with AWD componets it is combined with 02Q gearbox which means 240 mm clutch disk and possibility to use clutches and flywheels from 2.0 TSI CAW or the CCZ (and not BWA / BWJ due to the difference in the number of screws on the shaft)
  • There are rumors that starting from MY2010 all 1.8 TSI CDA engines are combined with 02Q gearbox ..

ZF Sachs Clutch Kit – Custom Made/Reinforced for 1.8 TSI BZB + KVT

Since the OEM clutch was not able to handle the torque I have ordered  ZF Sachs Clutch Kit – Custom Made/Reinforced – as this is the only option for BZB engine and KVT gearbox. The clutch is only available on request as there is not enough demand for it (the stock clutch easily handles remaped only setups) and it took me some time and a lot of emailing before I got it. According to the specification it should be able to handle 15% more torque compared to OEM clutch – so it should be enough for my current setup.

 

 

Cpanel addon domains and redirections

If anyone had a problems with cpanel addon domains and redirections (basically redirections defined by cpanel for addon domain are not working and we have several URL under the site is available instead of single one) you need to add following section to your .htaccess file:

  RewriteCond %{HTTP_HOST} !^(www.)?sevencoins.pl$ [NC]
  RewriteCond %{HTTP_HOST} !^$ [NC]
  RewriteRule ^(.*)$ http://sevencoins.pl/$1 [R=301,NC,L]

Replace sevencoins.pl with your site name. Basically the rule forces the URL for given web subdirectory to be set to defined one (as addon domains use subdirectories) .

Based on description found on:
