Connecting via SIP with a TAPI Bridge

Good Morning all.

So, I’ve hit a minor road block and I’m REALLY hoping the community can assist with this.

I have a legacy CRM application that used to connect to our old Dialer system via TAPI.

Now, I’ve searched and before a RC Official Rep says it, yes, I know, TAPI is not supported by Ring Central.

However, SIP is supported...

So, I have found SIPTAPI (Previously referenced and responded to by @Benjamin Dean).

However, it’s 9mths old and really does not cover anything about how and whether it could/can connect.

In principle, as long as I have SIP Domain, User, Password then all should be fine.

  • SIP Domain:
  • User: [my phone number]
  • Password: [My Password for RC]
  • Extension: [Optional]


However, it appears as though it’s trying to connect but getting either rejected from the SIP platform, or hanging for some reason.

Now, one answer might be that SIPTAPI is classed as a SIP device, and has not been authorised/cleared to connect – therefore it’s not gone through testing – and as I’ve not written it, that’s going to clearly be a problem.

It also might be, and the answer I’m very much hoping for, is that I’ve entered in the wrong information somewhere.

I did read that you log in with your AuthID and Password....but not seen any confirmation.


Can someone please help on this?

I could be wrong but if it's classified as a SIP Device by RC I would assume it would need to be authorized on the RingCentral side to connect as a device?  So you would need to add a MAC address for it and get an authorization id as if it were a non ringcentral phone?



SIP Domain

Outbound Proxy

User Name

full phone number, starting with 1 then the area code and number


UNbI9BEY – assigned by the system, changeable later

Authorization ID

60428140012 – assigned by the system

I haven't done this mind you it just seems like the next place to look.

I agree with Lee D, but also don't feel this is the best way to do what you are wanting to do.  It *may* work if you add a third party device and use the info and credentials from the new line though.  See here if you want to try: it shows where you will get relevant info like:
