If you are looking forward to having an IP Telephony business at some point you will get into the economics of the business. After all, it is a business and if you don't profit, there is no sense to do it.
When you are looking for your termination trunks (termination, in this case, is for outgoing calls from the point of view of your PBX), the idea here is to get the best carrier (if you are going to select only one) with the overall best rate.
It is not news that many people are searching for the not very new codec G.729. Since 2018 (please google it), the codec G.729 is not under patent, therefore you can use it without paying patent fees. This is a huge step for the VoIP work, why? Because the G.729 codec offers many advantages, one of them is the low bandwidth requirement; it needs about 11 kbps up and down each. If you think it, the less bandwidth required means your service will be more tolerant to the overuse of links. It is very common that in an office or a residence, more than one is watching any kind of streaming or downloading a big file.
Because of this, I think it is very important to tell the world how to install G.729 on your FreeSWITCH server.
Today, I am publishing the RPMs for SNGrep 1.4.8 All you need to do is to add my OKay's RPM repository, and just install it. SNGrep is a tool for displaying SIP calls message flows from the terminal. It supports live capture to display real-time SIP packets and can also be used as a PCAP viewer.
If you wonder what is the big difference from my RPM's, these have all the options enabled as much as possible. This RPM enables the HEP/EEP protocol, very handy if you want to use it to interact with Homer.
UPDATE: CentOS 6 is now at its EOL, therefore I am stopping any free update.
RPM's are available for Centos 7 and 8. And you can find it if you type yum search sngrep.
