Solved 408 Request Time - Vonage SIP

[Ruy]

Hello,

I just set up 3CX with my Vonage SIP and it registers ok, but when I try to dial out I receive request time out.

Firewall tests checks out ok. Can anyone help?

Hi Ruy,
Vonage is not among the 3CX Supported Providers. We strongly recommend using a supported VoIP provider with 3CX. The 3CX team makes sure that all listed VoIP Providers’ templates are updated and tested with every release ensuring no issues arise for our users.A list of 3CX supported VOIP providers can be found HERE.

Thank you for your response Apostolis. I understand Vonage is not supported by 3CX at this time however I see other people using Vonage under 3CX without any problems.

Is there anything under “general Voip providers” configurations on 3CX that you or anyone on the group can advise me to check in order to troubleshoot the timeout issue?

I am planning to replace Vonage, but it will
Take me a couple days and before perhaps having the same issue with another voip provider I was wondering if you could help me make sure that it’s not my set up that’s troublesome.

I followed the official guide to configure a “generic voip provider”.

Thanks so much!

Please note that since the timeout message comes from the providers IP you should contact your provider and ask them why you are getting this message. The generic voip provider template contains some pre-configured settings but that does not mean these apply to your provider. Obviously since this provider is not tested by us we cannot really advise what the correct settings are. Perhaps your invite contains info your provider does not like or requires this info on a different SIP field. A wireshark capture should help you confirm that the call is send to the provider and the message is coming from them.

Perhaps a user that has successfully configured Vonage can help you more with this.
You can also get a free account from a supported provider and test with that one to make sure that the PBX is working with a supported provider. Callcentric offers such accounts for example.

Hello,
I got a Callcentric account and number and am having the following issues:

Cannot call external numbers and see this on the log:
11/14/2017 6:10:54 PM - [Flow] Target endpoint for 97778679430 can not be built!
11/14/2017 6:07:38 PM - [Flow] Target endpoint for 99549402980 can not be built!

Heard this from Callcentric support:
Going over our logs; we are not showing any recent outgoing call attempts sent from your PBX (from a technical perspective, we are not receiving any SIP INVITE packets from your 3CX).

Besides the above the only other issues I see on 3CX's log are:
11/14/2017 6:15:42 PM - Exception: ParseException ParseBuffer.cxx:87, Parse failed Expected " " in context: Contents Messages-Waiting: no Message-Account: sip:[email protected] Voice-Message: 0/0 (0/0) Fax-Message: 0/0 (0/0) None: 0/0 (0/0) ^ @ ParseBuffer.cxx:87

And extension keeps registering and unregistering constantly:

So the first message means you don't have an outbound route matching your dial string. The other issue is a CallCentric specific and can be ignored per this thread: https://www.3cx.com/community/posts/210918/

Not sure about the extension, what is it?

 

[Ruy]

Thank you so much!! We arrived at a solution. Their guide (https://www.callcentric.com/support/device/3cx_version_15) which is what I was following was a bit off. As soon as they asked me to remove the string 9 from Calls from extension(s) and Calls to Numbers with a length of, it's now working just like a charm!!
Btw, no more parse issue on the logs - it's super clean now!!
You guys rock!! Thanks!

I just set up 3CX with my Vonage SIP and it registers ok, but when I try to dial out I receive request time out.

I wasn't aware that Vonage allowed you to bring your own device (BYOD), or gave you the password to even attempt to do so. They've always given the impression that they linked their hardware (locked ATA) to an account. Is this some sort of business offering?

 

[Ruy]

Yes it’s Biz Plan

I'm glad to hear that your issue was resolved.
