Asterisk Tutorial 10 - Incoming External Calls

Introducing Asterisk Phone Systems - Incoming External Calls

We’re back! After a short break, we are back with the latest in our Introducing Asterisk Tutorial series. Today, we have a quick recap on what we’ve done so far & Mathias gets serious by examining some real life telephony scenarios.

What that all means is that we briefly review what we’ve done so far, plus getting to grips with some more in depth dialplan configurations. We simulate receiving incoming external calls using a softphone. At this point, we could have added a SIP provider, but as this can be a complicated process, we decided to continue with testing steps before moving on to the more advanced stages of setting up your Asterisk PBX.

In order to simulate external callers, we need to setup a a new SIP peer in the sip.cong asterisk directory. The process is very similar to how we added our internal SIP peers, with the exception of the context. It is generally considered a best practice to define a new context [e.g. incoming] for external calls in order to prevent unauthorised access and usage of your telephony services.

The next step is to add the new context into your dialplan, and configure the context to jump to another context within the dialplan through using the Goto application and then reloading the dialplan and testing that everything functions as expected. Remember, when setting up your Asterisk PBX, testing every step is the key to ensuring not encountering problems in the future.

Stay tuned next week when we will take a look at some more Asterisk phone system real life scenarios and get going with simulating making an outgoing external call.

When we make decisions regarding new systems, we want to make sure that we have both reins firmly in our hands. Therefore, it is essential to implement systems which adhere to OpenStandards, allowing us to seamlessly connect and integrate these into our existing systems. In addition, we require reliable suppliers, who are ready to customise their solutions to our requirements, which is why we chose pascom who offer exactly this service and more.

We chose pascom as our telephony solution in part due to the scalability, flexibility and ease of deployment. In addition, the pascom platform functions perfectly with our digital guest directories in our rooms whilst offering the largest range of features at easily the most cost effective price compared to alternative solutions.

My team and I pride ourselves on the level of excellent care we provide our guests. However, it can be distracting when the phone is always ringing and we constantly answer the same questions. Thanks to the pascom phone system, we have been able to set up an automated attendant self-service hotline which allows guests to quickly get answers and if required callers can be quickly and efficiently routed to an employee. The system greatly improves customer service with around-the-clock answers around opening times and courses and therefore reduces the strain on employees, ensuring we are free to cater to the needs of our on-site guests.
