404 error when trying to call extension from another extension

General Help
1

Hi All, I have been struggling with this for a few weeks now, I have read all I can find on the 404 error but everything I can find seems related to incoming from providers not other extensions

Note (all ip addresses have been changed for security)
Below is the cli debug from the extension in question, it is extension 103, the call was placed from ex 101.

Calls from ex 101 to other extensions or external work fine
Nothing can place a call to 103 internal or external

The setup is freepbx is on a static public IP
I have opened and forwarded all recomended ports I can find.

Both extensions are behind dls nat routers, ex 101 is also a 7940 that is working fine so I believe the basic config is working ok

The 404 seems to be from the phone (cisco 7940), only other thing I can see in the log is a congestion problem?? But not sure how to interpret them really

This is the line info from the 7940 at ex103

SIP Configuration Generic File

Line 1 appearance

line1_name: "103"
line1_shortname : “Resource 103”

Line 1 Registration Authentication

line1_authname: “103”

Line 1 Registration Password

line1_password: "xxxxxx"
line1_contact : “103”

the phone appears to be registered ok
Name/username Host Dyn Nat ACL Port Status
103/103 213.121.131.184 D N A 5070 OK (309 ms)
110/110 81.131.84.235 D N A 5060 OK (19 ms)

101/101 81.153.185.96 D N A 5070 OK (319 ms)

Any pointers or guidance or help would be greatly appreciated.
let me know any othe info that may help
I believe the call is making it to the phone but the phone is rejecting it ??

Thanks Paul

kismet,

I’ll take a shot here but I could be off base without more background being provided by you.

Two of the three extensions you show as registered are using port 5070 which is NOT a standard setup. SIP by default is connected to port 5060 unless you have gone in and re-configured things. If so please post what you have changed, etc. That way we can see what else you might have missed.

If not please post more information on your setup. See http://www.freepbx.org/forum/freepbx/installation/so-you-have-a-problem-and-want-help for what we are looking for.

Thanks Fskrotzki

I had problems getting 5060 past the router for some reason if I left it as defaut it came in on port 1025 never did get to the bottom of that, so I moved it to 5070

There a 3 cisco phones set up 2 x 7940 and 1 x 7912, its the 2 7940’s that register on port 5070, one of them works fine its the one set as extension 103 where outgoing is working ok but I cant get any calls to it.

Below are the configs from the 7940

The software is FreePBX 2.5.1.5 but I think that is all ok as the other 2 extensions work fine.
My next step was to wireshark and confirm if anything was being blocked

Thanks Paul

ok I’m 98% sure this is all firewall issues. Since the phones you are connecting to are external and you have stated that you have firewall problems with 5060 I’m guessing that you are not configured properly.

So details on the firewall to start please.

You do realize that you need to open up UDP port 5060 and UDP 10000 to 20000 and forward all of them to the server. At the same time you need to create and add the needed lines in EITHER sip_nat.conf (old format) or sip_general_custom.conf (new format) and then reload. For details please see: http://freepbx.org/configuration_files

At the same time if there are firewalls at the remote locations they can be a part of the problem. Some older firewalls may need to have port 5060 forwarded to the phone.

Thanks Again
The server is on a public IP, only the phones use nat. mods to sip_general_custom.conf only seems to be needed when using the server behind nat, is this incorrect ??

It is firewalled but all the ports you specify are allowed.

The phone in question has been put in the DMZ of the router so realistically it should have no problems, I think I will go to the site and use wireshark to confirm if anything is being blocked.

Thanks for your suggestions
Paul

Not Managed to get to site yet but have done a bit more diags with the phone, these are the logs. it looks like the call is getting to it so the port forwarding seems to be working
this is extension 111 calling 112 again failing

couple of errors I can see are
