Hi DaveChomi , Mufarak 

 

I get the idea how it works but I think it is more than that because I am also doing integration with IP/PBX system and call transfer works well to this system extensions.

 

Let's say I have 2XXX format for Teams extension and 3XXX for IP/PBX system extension. When I am transferring the call to IP/PBX extension, it is working well without problems but not for Teams extension. It always shown "couldn't reachable" message when failing.

 

One more thing, I also thought that when I transfer call to Teams extension, it automatically recognizes the extension and not forward to SBC.

 

Any idea? Thanks.

HiAdityo Prabhaswara H. 

 

What is Line URI for users in Teams? is it just E.164 right?

 

Treat 2XXX and 3XXX as PBX extension and create dial plan normalization accordingly and send to SBC.

 

IF you set internal extension as false, then it will send to SBC as per route

 

If you want to transfer by Extension to Teams, you have to route the calls to SBC to process back with E164 Format as i mentioned earlier.

 

Check the pcap in SBC if you are sending to SBC for 2XXX
