How to see the event log for network / Wireless interface failure?


Open the Windows Event viewer (eventvwr.msc) and then within the View Menu enable the Show Analytic and Debug Logs options.


* Navigate to the WLAN-autoconfig event log. Since we enabled the Analytic and Debug logs option, beside the Operational log we also see the Diagnostic log.

The Diagnostic event log by default is not enabled, so first we have to enable it by right-clicking -> select Properties.

Business SIP SERVER Companies

The project hosts a public mailing list that can be used for business discussions:

  • business @ lists . kamailio . org

The Kamailio project maintains a directory listing companies and individuals offering commercial products, services or solutions based on Kamailio:

  • Business Directory maintains wiki pages about Kamailio consultants:

  • Kamailio Consultants
  • SER Consultants

Individuals and companies tightly involved in development of the project are offering telephony services (VoIP), consultancy, training, solutions and products:


Typical use cases:

  • standalone SIP server to provide telephony services for large subscribers base
  • scaling SIP IP PBX services (e.g., such as those using Asterisk PBX, CallWeaver or FreeSWITCH)
  • SIP Load Balancer and Failure Routing system
  • SIP Least Cost Routing system
  • SIP Trunking services
  • SIP SIMPLE Presence and Instant Messaging server
  • WebRTC integration to Kamailio and other SIP servers
  • development of new Unified Communication services and integration with Web 2.0

For further relations please contact the Management Team.

SIP Services
For those looking to get a SIP address, here is a list of providers that are know to use Kamailio or SER and allow public registration:

  • – maintained by few Kamailio developers (server located in Germany)
  • – maintained by few Kamailio community members
  • – maintained by SEMS developers
  • – maintained by Ekiga project developers

If you run a SIP service that uses Kamailio or SER and want to be listed here, write an email to our mailing list:

  • <sr-users [at]>

Implementing IPv6 Addressing and Basic
First Published: June 7, 2001
Last Updated: May 5, 2009
Implementing basic IPv6 connectivity in the Cisco IOS software consists of assigning IPv6 addresses to
individual router interfaces. The forwarding of IPv6 traffic can be enabled globally, and Cisco Express
Forwarding switching for IPv6 can also be enabled. Basic connectivity can be enhanced by configuring
support for AAAA record types in the Domain Name System (DNS) name-to-address and
address-to-name lookup processes, and by managing IPv6 neighbor discovery.
This module describes IPv6 addressing and basic IPv6 connectivity tasks.

Good document about VOIP telephony systems

Interconnection and convergence among PSTN, PLMN and data network are expected to
develop very powerful system; this system will provide PSTN services, mobility, PLMN
features and internet-based application. This convergence will support multimedia service with
adequate bandwidth and high mobility. The IMS technology is resulted from combination of
multimedia, mobile and IP concepts in order to complete the NGN technology [3,4].
.IMS acts as a standard platform for multimedia service through IP/SIP protocol with which it is
possible for the operator to use one’s platform for many multimedia service. IMS is a part of
arhitecture standard of Next Generation Network (NGN). Services for fixed, mobile and wireless
networks can be operated through IMS platform with IP based service and supported by SIP
protocol [1,5].

.Originally, IMS is developed for telephone connection in mobile network, but together with
TISPAN release-7, it is also has the possibility for fixed network, resulting term Fixed-Mobile
Convergence (FMC) which is a key industries trend in 2005 [5].
Software based on NGN architecture has been developed today. OpenIMS is constitute of the
software based on IMS architecture; it has the capability for various multimedia features.On the
other hand, Asterisk is a software based on softswitch architecture which is capable to connect
packet network and circuit network. With those both software, we can build a simple NGN
technology with lower cost investment.
To demonstrate the above cases, we design and implement a VoIP service, using the above
software, with the aid of Enum server which the function is to mapping the number among
