Most our clients have SPA 2102 boxes and we are using T38 protocol for faxing. Everything is OK, when faxing with speed 9600 , but the problem appears if another side supports only 4800 speed. For example, one my client wants send fax to B number. B side is connected over radio and supports 4800 fax speed for incoming and 9600 for outgoing. So what should I do? My SPA-2102 version is:
Software version: 5.2.10
Hardware version: 1.3.5(a)
Maybe somebody can advice which software version should I use to support 4800 speed?
Thanks for help
