Verizon calls are not coming in at times

[ag580108 (Agarcia)]

Here is the error I get when someone from a Verizon carrier calls our restaurant.
I have FreePBX 17.0.19.12
Can anyone help? I’ve been researching and changing settings around but have not fix the issue. We used to have FreePBX 16 and never had this issue. We used to use Chan_SIP
for our extension but FreePBX 17 does not support it. It supports pjsip for extensions

[2024-09-27 16:12:51] NOTICE[21972] res_pjsip_session.c: anonymous: Call (UDP:54.244.51.0:5060) to extension ‘+18568581807’ rejected because extension not found in context ‘from-sip-external’.

From extensions.conf

;-------------------------------------------------------------------------------
; from-sip-external
;
; This context is the default SIP context unless otherwise changed in the SIP
; Settings module or other sip configuration locations. This context is hit by
; either anonymous SIP calls or mis-configured SIP trunks when the incoming call
; can not be matched with a SIP section.
;

In your ‘sip settings’ you should have guest and anonymous calls disabled for security and to handle “Oasis Mexicang Gill” (sic) calls to +18568581807" you need an Inbound route named exactly that.

Is this what you mean for inbound routes?

[ag580108 (Agarcia)]

I disabled guest and anonymous calls

[dicko]

pretty well , the description is just a mnemonic, in your case to remember to have Zuppler Tech Team fix their typo

now watch sngrep for a call to that number

Two of the first call went through but the 3rd did not

Check your Match (Permit) in your trunk setup

[ag580108 (Agarcia)]

It’s blank, should there be an IP?

[Stewart1 (Stewart)]

You should list all the IP addresses from which your provider can send calls.

[ag580108 (Agarcia)]

It looks like adding the IPs from twililo onto the Match (Permit) fixed the issue, I haven’t seen any calls fail. I will keep you posted if any calls from Verizon fails.
