I am trying to installcompile ILBC support for asterisk. This tutorial will let you install the G729 Codec on an Asterisk installation in. Install G729 Codec for Asterisk. This small howto describes the installation G. G. 723. 1 codecs on Asterisk. GUIDE Free VOIP calls w i. LBC codec. UPDATE This may not work any more because Google said that they will cut off the Google Talk XMPP on 51. PBXES relies on. This guide is not about how to make free calls. Its about how to make free calls using i. LBC codec so that you can make reliable calls over 3g connection. If you only want the instructions, then skip to part V. I have changed my Vo. IP set up to PIAF on AWS EC2.

I. BACKGROUNDThere are several known methods to make free Vo. IP internet calls over 3g. Ill briefly discuss each to explain why theres no perfect solution. Im not claiming my solution is perfect, either. You have to try them out and find out yourself what works for you. Groove IP appcodec PCMU aka G7. PSTN and Google Voice, only good for fastreliable wifi connection pros simple setup, works well on wifi. If you use Vo. IP only on wifi, this is for you. The voice quality is terrible on mobile data 3g connection. Vonage mobile appcodec G7. SAC when calling a Vonage member. G7. 29 provides an excellent quality even on 3g. Android. You need to input 1. Google Voicepbxessipdroid http forum. Technique, If you choose speex codec for 3g, then call quality is pretty good on 3g.

I have been primarily using 4 setup but wasnt satisfied with the call quality on 3g so I was about to do 6. But I found a way to tweak 4 to use i. LBC codec and greatly improved the call quality on 3g. II. CODEC COMPARISONSThe call quality basically depends on 1 the codec that your phone uses and 2 the network throughput. Unfortunately, theres no perfect solution because of trade offs. PCMU 6. 4kbps is the uncompressed signal that is transmitted at PSTN. So it will give you the best quality as long as your network throughput supports it. This is the preferred codec for wifi connection. However, 3g network cannot consistently sustain 6. This explains why Groove IP works best on wifi but not over 3g. At the other end of the spectrum is GSM codec 8kbps. Its designed in 1. Its the most compressed signal, which is used by your regular GSM providers AT T, Tmo. These wireless providers allocate sufficient capacity on voice calls so your voice calls will suffer little jitter. However, the call quality is inferior to PCMU codec. There are many codecs in between. For example, Sipdroid and talktatone can use speex, which requires low bandwidth. These apps can send the same signal twice to compensate for packet loss. The 2 codecs that havent been used widely in commercial apps are G7. LBC. These 2 codecs require low bandwidth lt 1. It is suggested these 2 codecs are ideal codec for 3g connection. Here are some readings comparing G7. LBC. http blogs. In short, both are excellent codecs for 3g. LBC has a better quality but requires more CPU power, which Nexus 4 can easily handle. My setup relies on i. LBC. III. SETUPMy setup is an extension to 4 method above. It involves 4 free resources. Google Voice same phone number for inout calls and free outbound calls using gtalk2. Vo. IP provider for free inbound calls3. PBX that manages inout calls4. VOIP app that supports i. LBCOnce set up properly, heres how the incoming and outgoing calls will work. Incoming GV calls. Someone calls your GV number. GV forwards the call to callcentric. Pbxes intercepts the call and rings your phone. Your phone displays caller ID CID properly. Outgoing GV calls. You place a call in your phone dialer. Pbxes calls the number using gtalk trunk. The recipient will see your GV number as CID. IV. BENEFITSWhat are the benefits of my setup Completely free inout calls. You dont even give out any CC information. All Im paying is 3. Tmobiles 1. 00 min, unlimited data prepaid plan. Excellent call quality even on 3g using i. LBC codec. I often get better call quality than Tmos GSM. Keeping the same number for inout calls. Full Android integration. Battery life. Only requires 1 SIP registration to pbxes using TCP port. Battery stat screenshots after 1. V. INSTRUCTIONSAre you still with me Then follow these steps. Get a fast phone that can handle i. LBC codec. FYI, a 2 yr old Galaxy S has the sufficient CPU power for i. LBC. 2. Get an unlimited fast data plan such as Tmobiles 3. Install and set up Google Voice app on your phone. Without GV, you cant open a free pbxes account in 4. Install Sipdroid to create a pbxes account. When Sipdroid opens, it will detect whether you have GV app installed. If so, it will give you an option to open a free pbxes account linked with Google Voice. Create the pbxes account. In case Gmail flags for an attempted login, allow pbxes to gain access. Once you create the pbxes account, make test calls in and out using Sipdroid. Some ISPs may block you from using Vo. IP so make sure you can make calls before the next step. As of now, sipdroid doesnt support i. LBC codec so we will be using other sip clients for making calls. Log in to pbxes. org and click personal data. Fill out all the blanks. Doesnt need to be correct. If you skip this step, pbxes has been known to remove the account later. While you are doing it, I recommend changing the pbxes login password that you used in step 4 to something else. In addition, pick a data center server closest to you to lower latency. If you have registration issues, change to a different server. FYI, I had registration issues with www. Miami server. 6. Open a free phone number DID account at callcentric. You can only get a NY area code number but it doesnt matter because you will be giving out your GV number to your friends. All incoming calls to callcentric including GV forwarded calls will be free. You can decline E9. Download 500 Days Of Summer Movie In Hindi there. Callcentric supports efficient codecs such as G. LBC. We will be relying on i. LBC. The outgoing calls are not free but we will be using GV to make free outbound calls. Next, we have to link pbxes with callcentric so that pbxes can receive GV forwarded calls to callcentric. There are two ways to do this. If you are wondering why we are using callcentric instead of gtalk, its because pbxes has issues with i. LBC for gtalk incoming calls. Callcentric handles i. LBC better so we are piggybacking it. Callcentric call forwarding to pbxes. Log in to callcentric. Go to preferences DID forwarding. Input your namepbxes. AFAIK, callcentric doesnt charge call forwarding to a SIP address our method. However, it does to a regular phone number. Alternatively,7b. Have pbxes intercept the calls to callcentric.
