Hi Christer, Please see inline, Den 2019-08-25 kl. 11:23, skrev Christer Holmberg: > Hi Gunnar, > > .... > >>> So, what about the following text: >>> >>> "If an implementation needs to support multi-party scenarios, >>> implementations (both clients and servers) need to support multiple >>> simultaneous T.140 data channels, one for each source.

Isn't the T140block the data format? Currently yes, but a more complex format could be defined, e.g. with a structure containing a source indicator and the T140blocks with some separator or structure. Of coulse it would be best to have that structure in place already from the beginning in this draft, so that there will be no interworking problems when a source address is introduced. Or at least a specified way to extend the format.
