21 seconds drop | outgoing
Scenario: port 5060 blocked by ISP, port 443 used
NAT: no Optimize: yes STUN: yes Incoming calls: perfect Outgoing calls: all calls drop after 21seconds (even to 500 voice mail) Network structure :192.168.10.1 Router1 connects through lan to :192.168.10.10 Router2 connect through wireless to :192.168.10.100 computer with voip phone installed port forwarded in Router1 already tested. no results, keep droping. Any ideas? Thanks |
Try it without "optimize audio" on. I had a situation like this for outgoing calls with GizmoProject--and it cut off at roughly the exact same point (20 seconds), and it corrected itself when I set optimize audio to no.
Although if even *500 voicemail cuts off, then that perhaps would not fix it. Sorry, I don't know what to try next, other than playing with settings. I am in Canada, where I don't have to deal with aggressive attempts by my ISP to prevent SIP/Voip. |
Do not need to feel sorry. I must thank the attention you spent replying...
I tried Optimize "Off" and nothing. Strange because the inbound calls are perfect. May be the ISP blocking it but I already ready more people in this forum complaining about the same and I did not find any solution... |
So what SIP device (hardware or software) are you using? It would be interesting if you could troubleshoot using a different device (using X-lite softphone or another ATA or IP phone) to see if the problem reproduces itself with the different equipment. Because something is obviously confusing it with the firewall/NAT proxying.

Even the 500 voice mail call drops on 20 seconds I was wondering if the problem is the network structure: :192.168.10.1 Router1 connects through lan to :192.168.10.10 Router2 connect through wireless to :192.168.10.100 computer with voip phone installed -gateway: 192.168.1.1 I already forwarded the ports from 192.168.10.1 to 192.168.10.100 without success... |

or Try connecting to the first router directly just to test if the problem exists only when you are behind a second NAT This is usually a NAT issue, which should hopefully be made better by setting STUN.....(keep in mind you may have to set up port forwarding twice, one on each router as well...) Probably none of my business, but why do you need 2 routers....? |
Double-NATing is a common source of problems. If 192.168.1.1 is the first router, can't you get served up IPs in the 192.168.1.x range instead of going into the 192.168.10.x? I understand that your 2nd router is technically acting only as a switch, but why can't you make your 1st router a switch too and turn off its DHCP (since there is clearly a third router involved too at 192.168.1.1)?

blackrider, maybe your outgoing voice provider changed some of their settings, and because of that you need to re-tweak your Voxalot and SIP device settings from scratch to make it compatible again.

Thanks for your time replying to my questions... I really appreciate!
Sorry! The gateway is 192.168.10.1 first router is not wireless... the reason I am working with 2 routers. |
