thanks for the help, I discovered over the weekend that an option labeled &quot;SIP passthrough&quot; had been disabled. &nbsp;Turning that back on fixed the issue, but I also disabled SIP ALG via the command line on the router. &nbsp;Thanks again.

I've set up an Elastix server for a client, but I'm pretty new to it. &nbsp;I was able to get everything working with a local SIP trunk provider and incoming and outgoing calls were working fine.<br />
<br />
Just today, incoming calls will ring their phones, but when they pick up, there's no audio from either end. &nbsp;I also did some test outgoing calls to my cell phone; my phone rings, I pick up, but no audio from either end. &nbsp;The call stays connected the whole time, there's just no sound from either side. &nbsp;<br />

Being new to elastic, I don't know what else to do to troubleshoot. &nbsp;I've done the basics thus far:<br />

<div class="bullet">
Reboot main rounter

Reboot Elastix server

<br />
What should I do next?

Elastix: phones rings but no audio from either end

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.
