similar to: Echo on sip to sip call

I have the * server in a machine with two interfaces one internal (eth1) and another external (eth0), I'm in the internal side and when I put a call to another internal sip phone all is ok, but when I put a call to a external sip phone I hear the echo of my voice, a delay of 500ms.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list, I have a weird (?) problem here on a setup running CentOS 5.3 x86_64 (and OpenVZ, and some home-brew L2TP daemons, RIPd, BGPd, etc). There's a (VE in OpenVZ speak) virtual machine that has two ethernet interfaces, seen as eth0 and eth1, respectively. Those live in VLANs, but it's not important here. The thing is that on eth1 the

I have Asterisk running on my LAN with softphone clients (SJPhone) and Cisco 7940/60s, all using SIP. I also have a few remote sites connecting to my Asterisk server. I am getting an echo back of my voice when talking with one particular site. The caller does not hear an echo on their end. All calls on the LAN or to other sites do not produce an echo. When the caller places his SJPhone on

Our new * server with Cisco SIP phones is now working pretty well. But we still have one problem that has not been resolved. The Cisco SIP phones have a consistent echo. It sounds like about a 500ms delay. This echo is not heard from the POTS side. It is heard when calling another SIP extension in our office. We are running 6.3 firmware on the phones. Any suggestions would be

Thanks in advance! Summary: when I load netem and teql together, teql doesn''t work correctly. (If I load teql only, everything is fine) I loaded both netem and teql. Netem is associated with eth0, and teql is associated with both eth0 and eth1. But traffic only goes out of eth1. Attached are the commands that I used to configure teql and netem (on machine 1), and commands to

Hi All - I looked for mention of this in the archives but wasn''t able to find anything. This isn''t even an advanced routing question, it should be a dirt-simple, basic, no-brainer, routine routing job. But I''m not getting it! I have a Linux iptables based firewall system that is making me crazy. The gist of the problem is, even when I turn off all firewall rules

hi .. I have an asterisk system with three TDM100P (single port FXO) cards and 10 Grandstream 100 phones connected to it .. 1st question: when i phone out or receive a call from one of the SIP phones onto the PSTN, there is a LOT of local echo in the handset .. the PSTN end of the call does not here this echo, but it's VERY annoying on the SIP end of things .. the echo seems to be about 0.3

I want to route a wireless network
