  1. Solved Ghost Calls to Queue

    I found the queue in question was assigned to the sip trunk in the "general settings" of the sip trunk. As I understand it, when there is no inbound rule or did assigned to a queue, 3cx will route according to the settings defined in this section for the sip trunk. Originally (3 years ago) we...
  2. Solved Ghost Calls to Queue

    Thank you for the reply. I have reviewed the activity log but it didn’t reveal much. ive enabled verbose logging in hopes it will provide more info. And will follow up, the next time it happens. (Which should be tomorrow)
  3. Solved Ghost Calls to Queue

    For the past day or so, we've had a call queue receive ghost calls from multiple external numbers. There is no DID or Inbound Rule pointing to this call queue. The queue was setup a couple years ago, but never used as we opted to handle calls via a ring group instead. I'm trying to figure out...
  4. VM Greetings missing after backup / restore

    Did a full backup selecting all options (including recordings) from version 15.5 and restored to version 16 on a new instance. I am not finding that any of our vm greetings were carried over. Upon first launching 3cx console, I saw a blurb about recordings needing to be converted which I did...
  5. SMTP relay with Client Authentication failing ver 14

    Thanks for all the help. StefanW, can you point me to supporting documentation that the phone service is at risk by running v14? These instances are hosted w/ a 3rd party provider and I want to make them aware and get it upgraded. Thanks
  6. SMTP relay with Client Authentication failing ver 14

    Thanks. I was going to go down that route but didn't want to open the IP up for relay as there are alot of other instances on that ip that I have no control over and feared opening it up to spam. I suspect it may be trouble negotiating TLS and was hoping somebody could confirm that is an issue...
  7. SMTP relay with Client Authentication failing ver 14

    Thanks so much for the reply. No changes to Exchange server other than Microsoft Updates. ver 15 Instances delivers mail using same exchange server and authentication settings. (User Authentication for SMTP client submission). SMTP Logs on exchange server show: :42854,-,,Remote(SocketError)...
  8. SMTP relay with Client Authentication failing ver 14

    We have a hosted 3cx ver 14 instance with a 3rd party provider. We are using an on premise exchange server to relay messages from this instance using client authentication. For over a year this worked, then at some point it quit working. Ver 15 instances using the same exchange server and...
  9. 3CX compromised and toll fraud

    @cob Thanks for your advice. The Hosted PBX provider has an SBC on their end, but if I'm understanding your suggestion for disallowing extension outside of the Lan, I would need to deploy and SBC on premise as well? Is that correct? If so, I would probably want to find a gadget that would...
  10. 3CX compromised and toll fraud

    Thanks for the replies, If I select disallow use outside of the lan, how would my extensions on premise and on a different lan subnet connect to the cloud 3cx instance on its own subnet?
  11. 3CX compromised and toll fraud

    I had verbose logging enabled prior to this last incident. I see the ip (from Palestine) that registered and began making the fraudulent calls. I see a bunch of others that got blacklisted after 5 attempts. The previous compromises were from the same region, so I'm thinking this is the same...
  12. 3CX compromised and toll fraud

    Thanks for your reply, The PBX is cloud hosted with a provider. I have access to the admin management console and it has a strong password. Besides me, it would be the provider with access. During all incidents only a subset of the extensions were showing evidence of compromise not the...
  13. 3CX compromised and toll fraud

    We have some 3cx instances hosted with a 3rd party. Three times in the past six weeks are so, we have had extensions compromised and fraudulent toll calls were able to be placed until the sip provider noticed this and shut it down. (happened after hours and they caught it in about 4 hours)...
