What software can the landline of the hotel bar use to send the reservation message to the customer's mobile phone after receiving the reservation call?

This thing LZ said is the secondary development of SMS platform.

I suggest LZ contact the manufacturer of your management software ~ ask them if there is any corresponding function upgrade there ~

If not, LZ bar can be developed by someone if it is very large ~ ~ If the profit ratio is relatively low for me, it can be manually operated through SMS platform or Fetion ~ ~ ~
