I have 50 SIP trunks incoming through an SBC and I have setup my routing to use PBX1 as the primary and PBX2 as the secondary. Then I setup the PBX's with SIP Peer Profiles with a max call paths of 25 calls each(for resilience). My assumption was when I got to call 26 PBX1 would reject the call due to capacity and the SBC would then offer the call to PBX2. That is not the case call 26 is getting a busy. and when I do a packet capture it is showing PBX1 is rejecting the call, can't understand why the call is not then offered to PBX2.

Routing Inbound SIP Trunks through a Mitel SBC to more than one 3300

Assuming the SBC = MBG and not some other 3rd party device.
On the MBG, do you have your routing rules setup with Primary and Secondary controllers?

Assuming SBC = MBG as well.
If your setup is only one of resilience (PBX2 will get the load of PBX1 when PBX1 is down), then what you need is 50 trunks on each 3300s. Your MBG setup is correct but all 50 trunks need to go to PBX1. Only when PBX1 is dead that the call will fail over to PBX2. Yes, you need 100 MiVoice Business SIP trunk licences and it sucks.
I know since I have a similar setup here. Calls will ALWAYS be sent to the primary controler defined in your SIP trunk rules (inside MiVBG) as long as it is alive.
Sadly, MiVoice Business doesn't share SIP trunking licences in real-time as the need arise like MiVoice Border Gateway does.
This is for incoming calls.

@V3RTechNP - You only need extra licensing if you require all 50 channels to be in service All the time.
The design is fine as long as OP accepts that if a controller is out of service, the total throughput via SIP is reduced to 25 channels.
