Remote VoIP Phone Unifi Network

@JaredBusch Yeah, I'm relatively new with this client and trying to fix their most critical problems first. Agree, that needs to be upgraded.
-
Have you considered putting a VPN between the sites? That will remove the NAT completely.

@scottalanmiller - Agreed, especially if you have unifi at both sites it should be quick and easy (assuming they are on the same controller).
-
@NashBrydges - What phone are you using? Is it a Grandstream by chance?

Exactly, that's what I was thinking.
-
@scottalanmiller Yes I have, and given the phone is a Yealink, I think that capability exists however this is not my ideal workaround. I'd like to fix the actual problem without having to go VPN. But if there is no fix that I can find, I may not have any other choice.
-
@syko24 Yealink T57W

I've added the remote IP to the "networks" tab on FreePBX
My brain just caught up.
Remove this. It is not a "local" network because it is going through NAT.

I shoudl clarify that I don't want a site to site VPN. The only acceptable VPN solution would be the device VPN.

The phones have nothing to do with a site to site VPN between two routers.

Also go into the Asterisk SIP Settings and ensure that NAT is enabled for
chan_sipif you are using it.
-
@JaredBusch Yep, already set to that.
-
And if the extensions are
chan_sip, make sure the NAT is enabled there also.
-
@NashBrydges - Silly question but is the handset plugged into the correct jack on the back of the phone? I can't remember if the handset and headset ports are similar on the T57W.
-
@NashBrydges - just a couple other thoughts:
Do either locations have a double nat?
Who are the ISPs? Maybe something with the ISP provided hardware?

Yeah, the connections are good.

Both locations use the same ISP and no double NAT either.
-
willing to post pictures of your firewall configs?
-
What are your routers? Ubiquiti?
Can you disable SIP ALG on them? (sometimes called SIP transformation on other routers)

He mentioned CONNTRACK - I know that's on USGs.. not sure if it's called that on ER's?
OK the ER does have CONNTRACK.
