yup. So this is needed as it's possible that the established voice channel is not fully CTM-compatible (either because of network reasons, or because the called party does not have a TTY device attached, or does not have TTY support at all). In this case, the TTY property for the call would be FALSE (even if a TTY was attempted). And this is still standard procedure (applies to all GSM modems supporting CTM). _______________________________________________ ofono mailing list ofono@ofono.org http://lists.ofono.org/listinfo/ofono
