Are you Transcoding either side of the conversation ?

How do I tell? I'm just using the built-in call recording functionality of FreePBX 2.10

<div>
core show codecs<br />
core show translation<br />
<br />
To tell which codec is being used for a specific call use one of the following CLI commands:<br />
<br />
sip show channels

We are using Asterisk 1.8.8 and FreePBX 2.10. We record all of our inbound and outbound calls. When an incoming call comes in, the recorded conversation audio is off. The caller's audio will be correct and our internal conversation will be either very early or very late, which causes the audio to overlap in places and makes it very difficult to understand the conversation. If the conversation is over about 2 minutes long, the audio will eventually correct itself. I have updated SOX to the latest 14.4.1 and I am still having this issue. How can I fix this?<br />

Thank you

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).

Voice Over IP

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.

IP Telephony

Telecommunication occurs when the exchange of information between two or more entities (communication) includes the use of technology. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves. The word is often used in its plural form, telecommunications, because it involves many different technologies.
