VOIP.MS 403 Forbidden/INVITE

[pickgrand]

I am at a lost. I have had a system up for a few months with no issues. Today every outbound call gets "Forbidden by Administrator"

I am able to change the outbound parameters User Part: to
"outboundlineid" and "orginatorcallerid" and I can make calls for 2-3 minutes before it goes back to forbidden.

Below is the activity log:

12/24/2019 12:11:29 PM - Call to T:Line:10004>>740XXXXXXX@[Dev:sip:[email protected]:5060] from L:101.1[Extn:7047] failed, cause: Cause: 403 Forbidden/INVITE from 208.100.39.53:5060

12/24/2019 12:11:29 PM - [CM503003]: Call(C:101): Call to <sip:[email protected]:5060> has failed; Cause: 403 Forbidden/INVITE from 208.100.39.53:5060

However in wireshark dump we are sending the authid in the header per outbound parameters:
Here is VOIP.MS response:
We can't guarantee outgoing calls connect if our server is not receiving the username in the FROM header of the Invites. This is necessary so our servers allows the calls all the time. As you can see in the trace, it is not sending this but the callerID number instead.


Any help is appreciated

In the PCAP trace you should be seeing this response coming from the provider yes ? a 4xx response is a reaction normally to a client side issue so if the configuration has not changed on the PBX/Trunk settings you might want to look at your local firewall to the system to see if any NAT or SIP ALG/helper changes have occurred locally (changing SIP packet headers).

403 Forbidden means the server understands the request but is refusing to fufill it - this as you have identified could be authentication credentials, however could be IP related if these guys are an IP authenticated trunk perhaps - are they a supported 3CX provider ?

Thanks VOIP.MS replied with this:
"Please note that in your INVITE the callerID information is being passed in the FROM header. The CONTACT header seems fine now, but the FROM section of the INVITE is still not showing the correct information.

We expect the INVITE as follow:

Contact: < sip:[sipaccount]@[your_IP]:5060;transport=UDP >
From: "CallerID Name"< sip:[sipaccount]@[server].voip.ms;transport=UDP >;tag=b227be76
To: < sip:[Number]@[server].voip.ms;transport=UDP >

Where [sipaccount] is your subaccount
[Number] is the number you're dialing TO
and [server].voip.ms is our server (in this case chicago2.voip.ms)"

I was able to update the From User Part to: AuthID and it seems to be working now...

My question is if I used the "official" voip.ms trunk for 3cx why did I have to change this...

When you/they say callerID I am presuming they mean for example:
Call-ID: yesFZupcl03y51g-oWdyBw and not geographic number.

This caller ID is a unique identifier for the SIP dialogue messages nothing more - so as you have said you would need to alter what 3CX is sending to them - or they need to alter something their side.

My question is if I used the "official" voip.ms trunk for 3cx why did I have to change this...

You shouldnt - thats the point of having a pre-configured template so you dont have to change anything.
