Can't Connect to Sip Trunk

[Alex Sage]

What steps should I try to troubleshoot this?

There is a proxy, however I have added it to FreePBX.

The ports are open. I can't ping inbound35.vitelity.net, however with the proxy I am not sure if I should be able to or not....

[art_of_shred]

Is tcp correct? Shouldn't that be udp for that traffic?

[art_of_shred]

Instead of ping, try a traceroute to the server. See what it hits, where it stops, etc.

Um.... I think so? Sorry, I am not a SIP expert...

Vitelity has the settings required on their website although you need to specify both inbound and outbound. I think it should be UDP.

@coliver Beware the accuracy of what they list on their site. Try it, but you may end up needing to open a support ticket to get the most current settings. I've encountered that before, more than once.

That's right, I remember you guys saying something like that. It's unfortunate they can't keep those settings up-to-date.

Well that's not good. Maybe the proxy is in the way? or is it more likely a firewall issue?

Sadly, I don't have access to the firewall, but I have to email HQ.

traceroute to inbound35.vitelity.net (66.241.99.208), 30 hops max, 60 byte packe                 ts

I opened a ticket for the most up to date settings to use with FreePBX.

The question is: Were you able to get it going again?

[Alex Sage]

@dafyre No, still not working

[Alex Sage]

Sent a email to HQ to confirm the ports are open.....

SIP is TCP. RTP is normally UDP.

Do you have non-web traffic going through the proxy? If so, does it pass it?

It is? HQ said they opened udp only.....

You CAN do SIP on UDP. Not many places do.

[Alex Sage]

@scottalanmiller Well that could be a problem

[Alex Sage]

Just got a confirmation from Vitelity, they do use UDP.

Really useless. They use UDP for what? SIP (not normal) or RTP (normal) or both?
