We're in the UK, currently using ISDN30 to make and receive calls on our MiVoice Office 250.
We're attempting to switch a limited number of phones over to making their outgoing calls via 5 SIP Trunks so that we can trial making and receiving calls via SIP before increasing that to 20 SIP trunks, moving all outgoing calls to SIP Trunks and eventually porting over all of our incoming numbers and disconnecting the ISDN30.
We have:
- Subscribed to a BT WHC (Wholesale Hosted Communications) provider (5 SIP trunks + 10 temporary DDI's)
- Added 5 SIP Trunk licenses to our PBX
- Had the company that looks after our Mitel PBX configure it for us using the SIP Device Configuration Guide, May 2019
And now:
- We can make incoming calls to the first number in the block of 10 DDI's
- We cannot receive any incoming calls to the other 9 numbers in that block
- We cannot make any outgoing calls
When attempting to make an outgoing call, I can see from the packet capture on our firewall that we're getting a 404 User not Found response, but I don't know whether that means the number dialled should have started with the country code 44 instead of 0 (and how to fix that, if that's the problem) or whether this means there's a configuration problem at BT's end, or some other reason entirely why this isn't working.
I also have no clue as to why our system is only receiving calls for the first trunk number and not the other 9... they're not programmed anywhere in our PBX other than the Call Routing Table - I presumed that when our system registers for the first trunk number, that automatically routes all the numbers on our account to us... is that not the case?
Hope someone can make sense of this?
