Hi, What are the at!fm… commands? Are they documented anywhere? I gather they’re configuring the underlying Qualcomm baseband? —> These at!fm… commands are used to write and read data to a file in the file system. It is an internal document so I cannot share this externally. Yes, They are conf…

@newhouseeb WP7607 has modem with Volte or without Volte. few commands will not work on Non volte modem

@Donald Thanks a lot for your reply. I will check this once we receive the new set of commercial modems.

Understood. I wonder if we need to talk to Sierra Wireless or Qualcomm to get the appropriate documentation here? It also looks like you’re running a new, unreleased version of the firmware for the baseband: SWI9X07Y_02.32.03.00, whereas publicly there is only up to SWI9X07Y_02.28.03.05. Perhaps we…

Hi, I’m working as technical support for Sierra Wireless. What I shared is just a workaround. For production, you should not use that way. You should order correct SKU which supports VoLTE.

@Donald at !unlock, at!fmpath, at!fmw and at!fmr does not work with the WP7607 modem I have. Anyways, I succeeded to make the VoLTE woking in Automatic mode. However, When I force the modem to select LTE only (at!selrat=06) then IMS is not getting registered. How can I make the VOLTE working with L…

@shatrughan , The at!unlock and at!fmxxx commands are not accessible to users outside of Sierra Wireless which is why they did not work. All of the recently shipped WP76 units (in the last 6 months) have all had VoLTE enabled on them by default and should work pout of the box assuming they are conf…

@Matt I have received few new WP7607 modem today, which has old firmware: SWI9X07Y_02.18.05.00 000000 jenkins 2018/07/19 17:40:u7121: VoLTE does not work on this modem. Can you confirm if volte is supported on this firmware?

@shatrughan , Given the firmware version the unit is probably quite old meaning that it is not going to be enabled for VoLTE which is going to be your biggest problem as upgrading it will not help even if the firmware is capable. The unit cannot be enabled outside of the factory. Regards Matt

@mlw Thanks for the confirmation. is there any workaround to get this working with VoLTE? The unit SKU is 1104341 which does not seems to be too old. In that case, If I just upgrade the firmware, will VOLTE work?
