Yes, that is how those manufacturers that have paid royalties to Hayes are doing it. (Or perhaps the issue is just sloppynes of emulation; anyway, Hayes has a patent at that breakage sequence along with idle "safety" periods both sides of it.)
Like has been mentioned here recently (last week, I recall), if you have this problem, turn off the local modem escape by issuing AT S2=255 command before doing dialing; or dial by: ATS2=255DTnnnnnnnnnnn that is, prefix the dial command (DTnnnn) with escape disable command.
Check your modem manual for the S-register number, and disabling value. Document I used said 'escape is turned off with any value above 127'.
If the problem is at your ISP's side, then you need to inform them.
