<div>Hi guys,</div>
<div>I told my network admin to do what was advised in this thread. It works very well for incoming calls but outgoing calls hangup exactly after 20 secs everytime while displaying the following message on cli:</div>
<div> </div>
<div>v[Nov 19 10:26:26] WARNING[18617]: chan_sip.c:1910 retrans_pkt: Maximum retries exceeded on transmission <a href="mailto:dcc83eb7-4bd635cd@119.152.11.60">dcc83eb7-4bd635cd@119.152.11.60</a> for seqno 102 (Critical Response)<br>
[Nov 19 10:26:26] WARNING[18617]: chan_sip.c:1927 retrans_pkt: Hanging up call <a href="mailto:dcc83eb7-4bd635cd@119.152.11.60">dcc83eb7-4bd635cd@119.152.11.60</a> - no reply to our critical packet.<br> == Spawn extension (macro-rating, s, 104) exited non-zero on 'SIP/saad-a8b83300' in macro 'rating'<br>
== Spawn extension (macro-rating, s, 104) exited non-zero on 'SIP/saad-a8b83300'</div>
<div> </div>
<div>Also, this happens only with certain network conditions. in my office the outgoing call hangsup everytime but when i dial from home, both incoming and outgoing calls are fine. So i guess the problem is with user network configuration. asterisk for other users who are using different port to register is listening without any problems. </div>
<div> </div>
<div> </div>
<div>here is my network scenario(from where i make call):</div>
<div>we have a zyxel dsl modem connected to our ISP line</div>
<div>then we have a D-Link switch connected to the dsl modem</div>
<div>then we have sipura 2100 connected to that switch</div>
<div>IP addresses are in the range of <a href="http://192.168.0.0">192.168.0.0</a></div>
<div>NAT type on router = SUA ONLY<br><br></div>

<br></div>Mike,<br><br>I can confirm that it's working. Admittedly, I never looked at the<br>packets with tcpdump because this *just worked* for me. Calls that were<br>sent to both ports (5060 and 5062) made it to Asterisk which was only<br>
listening on port 5060. What's your experience with actual calls?<br><br>As the original poster, I understand if you want third-party<br>verification. I *thought* this was a slamdunk but I'm not an iptables<br>guru so I'd like it, too.<br>
<br>What does the output of "iptables-save" and "lsmod" look like? Here's<br>mine, trimmed for relevancy:<br><br>[root@asterisk ~]# iptables-save<br># Generated by iptables-save v1.3.5 on Thu Nov 20 12:03:21 2008<br>
