<div style="font-family:tahoma,;font-size:10pt;"><span><br></span></div><div style="font-family:tahoma,;font-size:10pt;">I want to do load balancing of two asterisk servers which are dealing with PSTN calls only, the script that I found on OpenSIPS website is a little complex and not my requirement. Let's say I have two asterisk boxes to be load balanced & whose IP addresses with allocated resources are added in the load_balancer table like:</div>
<div style="font-family:tahoma,;font-size:10pt;"><br></div><div><font size="2" face="'Courier New', courier, monaco, monospace,

<div><font size="2" face="'Courier New', courier, monaco, monospace, sans-serif">+----+----------+-------------------------+-----------+------------+-------------+</font></div><div><font size="2" face="'Courier New', courier, monaco, monospace, sans-serif">| 1 | 1 | sip:<a rel="nofollow" target="_blank" href="http://1.1.1.1:1111">1.1.1.1:1111</a> | </font><font face="'Courier New', courier, monaco, monospace, sans-serif"><font size="2"> </font><font color="#666666"><span style="font-size:12px;line-height:14px;white-space:pre-wrap;">pstn=32</span></font></font><span style="font-size:13px;"> | 0 | |</span></div>
<div><font size="2" face="'Courier New', courier, monaco, monospace, sans-serif">| 2 | 1 | sip:<a rel="nofollow" target="_blank" href="http://2.2.2.2:2222">2.2.2.2:2222</a><span style="white-space:pre-wrap;"> </span> | pstn=50| 0 | |</font></div>

<div style="font-family:tahoma,;font-size:10pt;"><br></div><div style="font-family:tahoma,;font-size:10pt;">So what will be the possible changes for load balancing script or will the below simple load balancing script/function will work for me:</div>
<div style="font-family:tahoma,;font-size:10pt;"><br></div><div><font face="'Courier New', courier, monaco, monospace, sans-serif"><font size="2">load_balance("1","pstn");</font><br>

Thanks in Advance!!</div><div style="font-family:tahoma,;font-size:10pt;"><br></div><div style="font-family:tahoma,;font-size:10pt;"> </div><div style="font-family:tahoma,;font-size:10pt;">
