mncc: Enable in-band signalling for early media
Besides sending the alerting request we should inform the MS that there is in-band information now. We do not seem to export these flags in protocol/gsm_04_08.h so hardcode them for now (until I come up with good names for them). Related: OS#1784 Change-Id: I80b1e1f4ca045bd63536476702a5812f27d9b36d
