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).
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.
