They have lock the router , i cant make Nat or port forward. The only that i have make is to open the port 5065 and any traffic in this port is going to my elastix , but i see only request send in sip info .
Hi , thanks for your time . My connection is adsl from hellas on line.
The router is one that it give me isdn number but i have no access on it because is lock .
I ask them to open the port 5060 to work with that and they told me it can not be open because they work with this one and with 5061 and i must found another port to work.
Hi , first of all thanks for the help.
The modem have only the name of my isp , so no brand name on it .
Can any one tell me how i can change the port that asterisk communicate with my sip voip provider ? I have try any think that i found in Internet with out success.
P.S my VSP not allow vpn and they dont have IAX SERVICE.
Hellas on Line in Greece supplies the end user with a preconfigured adsl router featuring 2 sip based fxs ports on the device !
The facility is implemented but, for some reason, was never officially offered as a solution by the isp ... but that is another story !!!
All you have to do is buy a new dsl router and you are ready to use any port you wish !
The price should not exceed 50 euro !!
In our country many of ISP are blocking SIP ports, please tell me is there any way to pass traffic through Port 80 rather than using port 5060 (As Skype using port 80).I think by using Sip Proxy server.
Any one had configured Sip proxy Server for their Netowrk ?? please share your knowledge.
Hi , thanks for your time and help one more time .
Now i can not change the router because this adsl router provide me with isdn protocol .
I will see today if my VSP can work with another port , if not i will change the ISP , they must learn that when i pay they can not lock router, ports or any think else . When we make the deal they DINT SAY ANYTHING ABOUT LOCK !!!!.
If your ISP only blocks 5060 port (or to put it another way, your ISP doesn't block all UDP ports), you can use SIP outbound proxy server to bypass the blocking. SIP messages will be sent to the proxy server first through non-blocking ports and then be forwarded to VOIP provider. Check www.sippp.com
However, if your ISP does packet filtering and drops SIP messages, you need a VPN-based solution. Check www.vpn4sip.com
If only 5060 blocked, try a SIP outboud proxy server. SIP messages will be sent to the proxy server first through ports which are not blocked and then be forwarded to VOIP service provider. You may want to check www.sippp.com which provides SIP outboud proxy service. It also works with end-users behind NAT.
If your ISP does packet filtering and drop SIP messages, you have to go to VPN-based solution.
