<div dir="ltr">Hi Steve,<br><br>It's behind a NAT/Firewall but SIP translation is enabled and removing it from behind the firewall did nothing, it still dropped calls. The calls connect and everything works, but it dies when all trunks are in use and someone else tries to call out. It seems like even though both channels are in use, it tries to connect to the 2nd trunk and thus kills the audio. Nothing strange came up in Wireshark or the firewall logs.<br>
<br>Thanks.<br><br><div class="gmail_quote">On Fri, Oct 10, 2008 at 5:40 PM, Steve Totaro <span dir="ltr"><<a href="mailto:stotaro@totarotechnologies.com">stotaro@totarotechnologies.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

<p><span style="font-size: 10pt; font-family: Arial;">We have 2
SIP trunks from Bandwidth.com and if both are in use and someone tries to dial
out, they cause another call to get one-way audio (the caller hears us, we
cannot hear them). This happens 100% of the time and Bandwidth.com doesn't
offer any support. I don't see any setting that tells Asterisk that there are 2
channels available from Bandwidth.com's IP. I'm currently using, or attempting
to use, groups to solve this problem, but sometimes it works, sometimes it
doesn't. It breaks when a call goes out on a Queue, because it seems to add
each phone to the group, which breaks my GotoIf() statement. Here's some
relevant information:</span></p>
