We have a customer to has an AS5350XM with digital modems which is used for PSTN/ISDN dialin via a PRI line.
The customer is asking if theres any way to "force" the initial modem speed via the incoming called number with the idea being to try and reduce the time to connect via avoiding the modem speed negotiation down from 56Kbps.
Now we can obviously set up different ASYNC groups to set the speed to we're struggling to understand how to map this to an incoming numbers.
Has anyone any idea how to do this ? I have a feeling this may be the ISP mapping certain numbers to certain channels on the ISDN which will then have a specific group-async attached.
