<div dir="ltr">Hi,<div>i am not sure how Freeradius server works but seems problem is with server . as with mox_xml_radius we are doing 1000+ calls with media and have gone upto 5000+ calls without rtp and never ever had issue with Radius server and mod_xml_radius communication . They work perfect . </div>
<div>so may be some config issue or definitely freeradius issue .</div><div><br></div><div><br></div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Fri, Mar 7, 2014 at 8:07 PM, Ričardas Stoma <span dir="ltr"><<a href="mailto:ricardas.stoma@gmail.com" target="_blank">ricardas.stoma@gmail.com</a>></span> wrote:<br>
