Sounds like a misconfiguration or a bug in the Ericsson to me. The switch should be able to tell the difference between a 1 and a flash. Further, you imply that OTHER numbers can be pulse dialled, indicating that pulse dialing IS supported. I suspect that the person who configured your Ericsson figured that no pulse phones would be used, and they set the flash interval so small that it cannot be distinguished from a 1 (our old ITT 3100 PBX could be so configured). It makes flashing easier: you don't have that annoying problem of trying to flash but realizing that you haven't held the hook down long enough. Used to happen to me all the time until I convinced our ITT maintenance people to change the flash interval; it was ridiculously high. Never encountered these problems with our current AT&T System 25. The defaults are apparently just right.
