Hello i hope you can help me with the next problem :
I have one endpoint E20 with one ip 213.149.... and i want to call an ip behind a router with inner ip 192.168.1.227 .The VCS and the MCU are behind the same router with ips 192.168.1.248 and 192.168.1.221 .When i try calling from 192.168.1.227 to 213.149.... it calls but when i try calling from 213.148...... to 192.168.1.227 there is no result. I have opened the ports 5060 ,5061 and 1719 on the router. I hope that i have explained it correctly. Thanks for the help you are great!
Issue you are facing is expected beheviour , You can not call private IP 192.168.x.x from public IP . Private IP are not routable from internet .
To achieve that you will need a VCS-E in addition to the VCS-C (or a VCS-E starter pack instead of the VCS-C) - and have the appropriate DNS SRV records in place. Strongly recommend taking a look at:

This is how it looks like When i try calling from 192.168.1.231 It calls without video but with audio,and when i try calling from 22.214.171.124 cannot connect call. Thanks again
I guess you are dialing from e20 (192.168.1.231) to e20 (126.96.36.199) using it's IP not URI, correct?
Now if you are dialing from e20 (188.8.131.52) to e20 (192.168.1.231) then you have to use its URI as registered on the VCS expressway. For that to work make sure the DNS SRV records are in place so that _sip._tcp.proba.bg resolves to the VCS expressway public IP.
In other words the sip request to call, say email@example.com, should be resolved by he public DNS sevrers and hit the VCS public IP address.
What is the router thst is doing NAT? IOS and model?
i'm dialing the uri of the e20(184.108.40.206) on the phone System information there is : Sip Status: Registered. It calls the phone but the e20(220.127.116.11)doesn't send video and audio to e20(192.168.1.231). The router is just for testing TP LINK TL-WR740N. The other router that will be on it's place is Cisco 2900 series.
I think i can explain it better in bulgarian it will be great if you can give me skype and help me out with this if you have time. Thanks for the fast replay and regards!
Hi Svetoslav Simeonov,
It could be a issue with the firewall port openings. Please ensure that you have proper ports opened.
Although for this kind of solution vcs-exp is required or you put vcs-ctrl on the public ip.
Thanks for the replay! I have opened ports :
I don't have any vcs expressway ... Thanks again.
its not very clear from which direction to which direction you have opened the ports.
when you make a call frm E-20 reg to VCS-cntrl the call will be dialed out thorugh VCS control and will be sent out as H.323 call to remote endpoint.
I am not sure but when you make a call from E20 what is your source protocol sip or H.323? in case if you do an interworking then VCS shall take the media.
