Using SER with Xlite softphone (either v.1.x or 2.0) through the Internet, one-way communication is experienced by the UA (only outgoing traffic is possible). The UAs are connected to the Internet via public IP address and no firewall is enabled. The problem has been replicated with 3 different users, over 3 different ISPs. However, the same users, can always communicate without problem over the same connections, using Windows Messenger.
In both cases, I have captured (ngrep) the SIP packets from the server port (see here after).
The topology of the SER and UAs, is as following:
UA1 -- public IP ---- Internet ---- NAT -- ATA186 (Xlite) (dialup) | (DSL) or | (Win Mes) | | Router(NAT) | DMZ | SER (listen on 5070 udp)
Could anyone take a look in the packets for Xlite and Messenger and see what makes the first one acting as being behind a firewall, while Win Messenger is working properly ???
Thanks, George
PS. Xlite is working properly with the SER in Intranet environment.

Hi,
This isn't a solution to your post. I just have a couple of comments that I think will help with your debugging.
At addaline.com we have partnered with Xten. Xten works for us public/public, public/nat and nat/nat. We are using Jasomi for NAT traversal. The only 'trick' is to get the 'Send internal IP' checked.
I have (over the last year) debugged quite a few problems, usually with my understanding or configuration. I have found that sipscenario is much better to examine packets than ngrep. Looking at the ngrep output isn't much better than tcpdump...the sipscenario uses ethereal (or tcpdump) and creates a real nice call flow chart (for example: http://www.august.net/oneway1_index.html
I don't know where this software is these days, you can contact ray.elliott@ipc.com if you are interested in a copy.

Using SER with Xlite softphone (either v.1.x or 2.0) through the Internet, one-way communication is experienced by the UA (only outgoing traffic is possible). The UAs are connected to the Internet via public IP address and no firewall is enabled. The problem has been replicated with 3 different users, over 3 different ISPs. However, the same users, can always communicate without problem over the same connections, using Windows Messenger.
In both cases, I have captured (ngrep) the SIP packets from the server port (see here after).
The topology of the SER and UAs, is as following:
UA1 -- public IP ---- Internet ---- NAT -- ATA186 (Xlite) (dialup) | (DSL) or | (Win Mes) | | Router(NAT) | DMZ | SER (listen on 5070 udp)
Could anyone take a look in the packets for Xlite and Messenger and see what makes the first one acting as being behind a firewall, while Win Messenger is working properly ???
Thanks, George
PS. Xlite is working properly with the SER in Intranet environment.

Hi,
This isn't a solution to your post. I just have a couple of comments that I think will help with your debugging.
At addaline.com we have partnered with Xten. Xten works for us public/public, public/nat and nat/nat. We are using Jasomi for NAT traversal. The only 'trick' is to get the 'Send internal IP' checked.
I have (over the last year) debugged quite a few problems, usually with my understanding or configuration. I have found that sipscenario is much better to examine packets than ngrep. Looking at the ngrep output isn't much better than tcpdump...the sipscenario uses ethereal (or tcpdump) and creates a real nice call flow chart (for example: http://www.august.net/oneway1_index.html
I don't know where this software is these days, you can contact ray.elliott@ipc.com if you are interested in a copy.
Regards,

Using SER with Xlite softphone (either v.1.x or 2.0) through the Internet, one-way communication is experienced by the UA (only outgoing traffic is possible). The UAs are connected to the Internet via public IP address and no firewall is enabled. The problem has been replicated with 3 different users, over 3 different ISPs. However, the same users, can always communicate without problem over the same connections, using Windows Messenger.
In both cases, I have captured (ngrep) the SIP packets from the server port (see here after).
The topology of the SER and UAs, is as following:
UA1 -- public IP ---- Internet ---- NAT -- ATA186 (Xlite) (dialup) | (DSL) or | (Win Mes) | | Router(NAT) | DMZ | SER (listen on 5070 udp)
Could anyone take a look in the packets for Xlite and Messenger and see what makes the first one acting as being behind a firewall, while Win Messenger is working properly ???
Thanks, George
PS. Xlite is working properly with the SER in Intranet environment.
