These macros shouldn't end with a ; because it breaks some compilers (ask smcv for details).

Not in Telepathy style.

Weird indenting.

Similarly both for get_property()

TpBaseChannel already implements TpSvcDBusProperties, you can use tp_dbus_properties_mixin_implement_interface()

Personally, I don't think SMS needs to be a separate feature, that it's worth just having in CORE.

is-sms-channel ?

missing goto finally; ?

Right, I already experienced that as well; removed.

Oh good point; done.

The general philosophy is to restrict CORE as much as possible. Users won't
have to care about the SMS feature as most of them will use the default
factory preparing this iface (actually I forgot to add it but I did now. :)

renamed.

Ooops; fixed.

Consider squashing before merge.

The comments refer to properties added in #36334. We should get that merged too.

Rebased, I'll push once bug #36334 is fixed.

Fixed and merged to master; will be in 0.15.1
