Setup external Virtual Pbx

24
Nov

 A Private Branch Exchange is one of the must commonly used by Business users, to route and manage incoming, and outgoing calls into a business call system.

The purpose to use a PBX is:

  1. Handle an Interactive Voice Response, IVR system, to welcome incoming calls, and handle them into an interactive channelization into the business destinations;
  2. Manage incoming call waiting, call transfer, and other internal call system inside the company;
  3. Manage outgoing calls, extensions inside the company environment privately and upon the permuted public network.

In SipCel, we don’t provide such as standard feature in box, but we provide it on demand. What’s mean:

  1. If you require to connect several extensions into your business, you may just request additional SIP users, and you will have whatever users to connect to your account for FREE;
  2. If you require virtual voicemails, you may just request to add whatever voicemails to your sip users;
  3. If you wish to route incoming calls into your users, within certain priorities, you may just configure your DID on demand, for FREE;

But, if you require further features, we may not provide you:

  1. IVR;
  2. Internal Call Waiting;
  3. Internal call routing;
  4. Work flow call reception;

For all over that features, you may request our Virtual Private Circuit Service, or use any other Free or commercial external service, such as pbxes.org, myvoipapp.com, sipsorcery.com, mysipswitch.com or whatever other which you may find online, you’re FREE to choice as you like, to do that, you have to take in mind the following:

  1. From SipCel you need to connect only within one single SIP Account to your remote switch;
  2. To your remote switch you have to connect all over your extensions/ users, what mean, that into your end point and SipCel network it will be that remote switch, so take in mind that you’re really choosing an appropriate service, within serious network capacity, as this will handle your traffic, and my reduce SipCel service quality. We don’t take responsibility upon the service quality loosing, or any further support.
  3. It’s highly recommended that the remote switch should have a static IP, if the remote switch don’t provide a statical IP host, it’s really no sense to turn into a remote pbx within dynamic host ip, if you do, it’s mean that really you don’t do what are you doing!!
  4. To your remote switch you need to appoint all over your incoming DIDs directly, within the format SIP/whatever-identification-you-like-to-read-in-your-remote-swith@your-remot-host-ip. For example, if you have the DID: 902918088, and you will appoint it to pbxes.org, you may first insure that you have the remote pbxes.com host ID, when you have it, you need to login to the customer portal, under the DID tab, appoint your DID as a voip destination, priority 1, to: SIP/902918088@pbxes.org, and in pbxes.org you may configure your incoming DID as 902918088, and turn it into your swich as you like into your IVR and internal extensions.

Simple example: You have a small business, where you need to connect 7 users within 7 desktop extensions, and 7 mobiles

Common INCORRECT practice:

  1. You request from SipCel for 14 sip users, and you connect all over that 14 sip users to your remote pbx, and then you connect your users to that remote PBX. Conclusion, you really have no idea what are you doing, you will wast your time, the service quality and all over your business telecommunications.
  2. You appoint your DIDs to your sip account, which are appointed to your remote pbx, and from there are turned again to your local extensions, and by end, your call progressing are increasing, and you’re going to loose 90% from your incoming calls into call progressing time. This is the typical misunderstanding!

Correct practice:

  1. You get by default from SipCel for one single Sip user, you create that user as a Sip Trunk into your remote switch, and into your remote switch you create 14 extensions, to connect your users, and turn your incoming and outgoing traffic into your switch, and send it to SipCel into your single Trunk.
  2. To connect your sip trunk to your switch, the correct is that you have your remote pbx within a static Ip (Phix Ip), so you raise a ticket to SipCel support to turn your sip account to IP based authentication, and you setup your remote pbx as a single IP trunk within IP based authentication, that will improve considerably your service quality, progressing time, and reduce connection failing.
  3. You appoint your DIDs directly to your HOST Ip, where you turn your calls under your remote IVR, and into your local extensions. This will improve considerably your incoming calls, and decrease the Progressing time, and guarantee in all time your calls reception, and correct handling.

Important Considerations:

  1. It’s NOT recommended to whatever virtual switch, as first of all, you have no idea where is your remote switch is located, that will not guarantee you correct connection, and configuration. SipCel offer you 5 geographical connection point over the world, resolved over the nearest DNS, if you connect directly to our network, you are always guaranteed within the nearest connection. Imagen, if you’re in Madrid, and travailing to Israel, and you decide to use your virtual switch within X company who offer you a cheap, of Free PBX in US, your calls are going to be handled from SIP to US, and then to your handset in Israel. Consider this call progressing time, and quality loosing, this is serious!
  2. SipCel handle the mobile devices over standard and official G729 licenses, to reduce bandwidth, and guarantee service quality. Do you think that a cheap, or free pbx will offer you seriously a standard, and official codec processing? Consider what are you doing, in SipCel this service is included in box, and we’re not going to charge you nothing for it, our main interests is the service quality, not to sell you whatever bottled air!
  3. In SipCel we offer network redundancy, and 24/7 technical support service, for FREE, consider if you put in the middle another free service, which you have no idea who is managing, and the possible failing which could happen.
  4. It’s highly risky to put your account credentials and your business telecommunication service into a remote virtual switch which you have no idea who’s managing it, and which security protocol are supporting, if your account details are gone, it’s mean, your account balance is gone also. If your customers calls are gone, it’s mean, that your business will be subject to liability upon your local privacy regulation. Consider what are you really doing!
