Hi, On one of our locations, I am having issues with one-way audio when I call several phones with SIP/Phone_A&SIP/Phone_B&SIP/Phone_C. When I call the phones individually, they work fine, so it's not a volume setting on the phone. Also this setup has worked at other locations. Any idea's what to look for? Thanks in advance. Kind regards, Roland. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.digium.com/pipermail/asterisk-users/attachments/20120624/eb78eefa/attachment.htm>
