MAX HD2 MBX - various questions

I haven´t been able to find the answers to the following questions from a potential MAX HD2 customer:

Does it support VoLTE + Vo5G?
Will it be able to function as a voice gateway?
Will it run 5G frequencies on both WAN connections?
Will it be able to support and run 3G and 2G? (compatible)

Great help if any of you could help with answers (and perhaps experiences with the topics)


Hi welcome to the forum!

No, there is no inbuilt support for VoLTE + Vo5G. It has SIP ALG of course but does not act as a VoIP Gateway.

the HD2/HD4 MBX is generally available with either CAT12 or CAT18 modems. I know partners are testing CAT22 modules which have support for 5G NR frequencies.
The CAT18 modems are Telit LM960A18 modules which support:
• LTE FDD: B1, B3, B25(B2), B66(B4), B26(B5/B18/B19), B7, B8, B12(B17), B13, B14(FirstNet), B20, B28, B29, B30, B32, B71

• LTE TDD: B38, B39, B40, B41, B42, B43, B46, B48 (CBRS/OnGo)
• 3G B1, B2, B4, B5(B19), B8, B9

You can do an in place upgrade of the modules to 5G later when / If needed.

3G yes, 2G no.
