Connecting two trixbox CE systems together using vs .net toadd code128b in asp.net web,windows application Bar Code Scanner Environments At some point you Visual Studio .NET code128b may want to connect branch offices together, connect directly to a business partner"s system, or may want to have multiple systems in different parts of your organization. There are numerous methods to accomplish this but we will focus on a simple method that will accomplish the following goals: Allow extension to extension calling Properly pass caller Be simple to set up.

First off, let"s c reate a table that gives the details of the two systems that we will connect together.. Parameters Extensi barcode 128a for .NET on Range Public IP System 1 3000 3999 10.10.

45.50 System 2 4000 4999 24.7.

72.71. [ 136 ]. Download at Boykma.Com 8 . Within the PBX Con code 128 barcode for .NET figuration tool, we can now create a very simple trunk that will allow us to place calls between the two systems. System 1 Create an IAX trunk: Trunk Name: InterOffice PEER Details: Qualify=yes type=friend host=24.

7.72.71.

Leave all the rema ining fields blank. Create a new Outbound Route: Dial Patterns: 4xxx Trunk Sequence: IAX2/InterOffice System 2 Create an IAX trunk: Trunk Name: InterOffice PEER Details: Qualify=yes type=friend host=10.10.

45.50. Leave all the rema code 128 code set c for .NET ining fields blank. Create a new Outbound Route: Dial Patterns: 3xxx Trunk Sequence: IAX2/InterOffice After saving and applying the configurations on both systems, you should now be able to place a call between the two systems.

. [ 137 ]. Download at Boykma.Com Advanced trunking DUNDi From the Asterisk website: DUNDi is a peer to peer system for locating Internet gateways to telephony services. Unlike traditional centralized services (such as the remarkably simple and concise ENUM standard), DUNDi is fully distributed with no centralized authority whatsoever. DUNDi is not itself a Voice over IP signalling or media protocol.

Instead, it publishes routes which are in turn accessed via industry standard protocols such as IAX, SIP, and H.323. DUNDi can be used within an enterprise to create a fully federated PBX with no central point of failure, and the ability to arbitrarily add new extensions, gateways, and other resources to a trusted web of communication servers, where any adds, moves, changes, failures, or new routes are automatically absorbed within the cloud with no additional configuration.

When you are connecting more than two systems together, DUNDi may be a more appropriate method, as it is not only used for creating a simple trunk, but can be used to create branch offices that place their phone calls through one central phone system. Since DUNDi is rather difficult to configure, and there is no web interface available to configure it at this time, we will not cover DUNDi trunks in this chapter..

Handling emergency calls Something to alway s consider is how to handle calls to emergency service (911 in US). In cases where we don"t have a PRI circuit with plenty of extra capacity, I simply recommend having a single POTS line that has its own trunk and whose only purpose is for 911 calling. For many people, the monthly cost of a dedicated phone line that is reserved only for emergency use is a little expensive.

For companies with remote users, it doesn"t take into account a phone at a remote location that dials 911. In this case, emergency services would be dispatched to the address of the company and not where the remote user is located. One built-in solution is fairly simple to set up although it does require that your telephone service provider will allow you to override outbound caller ID.

While some SIP trunk and PRI/BRI providers will allow you to override the outbound caller ID, you should check with your provider to see if this is possible with your service.. [ 138 ]. Download at Boykma.Com 8 . Let"s say that And rew works at home in New York and we want to make sure that if someone grabs his office phone and dials 911, then it gives the emergency service his actual home phone number instead of the phone number of the company, which is in California. We edit his extension and in the Emergency CID field, we enter his phone number of <2125558534>. We then go to our Outbound Routes configurations and add a new route.

Let"s use the following settings to create an Emergency routing table: Route Name: Emergency Emergency Dialing: Yes Dial Patterns: 911, 9. 911 Trunk Sequence: Select the trunk to dial out on. There are also thi rd-party 911 services that can help manage remote and mobile users. One service like this is 911Enable (http://911enable.com).

With a service like this, you create a SIP trunk to its system and route all 911 calls through it. You then have to manage a database of your users through its web interface to let their system know where all of your users are located. Mobile users can even log in and update their information themselves if they are travelling.

When a 911 call is routed to it, it is routed to the appropriate emergency services provider in the area that is local to where the caller is located. This will provide the best quality emergency service available..
