Hello All,

 

Trying to interconnect my Telco Provider PSTN  with Microsoft Teams via SBC Audiocodes.

It is a PoC hence I used a SSL certificate issued by Trial Thawte CA.

The IP group connected to the public IP (the one connecting to Teams) is in disconnected state (basically it does not get access to sip.ptsnhub.microsoft.com, sip2.ptsnhub.microsoft.com or sip3.ptsnhub.microsoft.com)

I suspect the reason is the certificate I used.

Could you please advise on the above?

Cheers beppe

I have no answer for your. I just want to follow this topic, as I might have to do that soon too.

Did you get them to lent you the SBC appliance for the PoC?

Nope,

 

But you can download an evaluation from their site and install it in a virtual environment (either hyper-v or vmware). After you'd need MSFT license though.

Oh , thanks. I will look again at their website, but I haven't seen that before. Buying one or two Cloud PBX license should not be a big deal.

Any progress on your issue?

No progress. You could use a trial version of Office 365 E5 (it is free). It lasts for 30 days as far as I know, but that spell of time might well suit you in terms of a firts hand on experience.

Hi,

Since Trial Thawte CA is not listed as an trusted certificate authority that could be an problem. If you want to use a certificate from Thawte it has be issued by Thawte Timestamping CA.
