Hi,
we test voice branch also with the Huawei ME-909s-120 modem with 
firmware 23.613.61.00.00.

This modem/firmware provides a new unsolicited command (^CSCHANNELINFO) 
received twice between ATD and OK replies.
With this sequence MM parser seems to miss the "OK" reply.

In order to resolve this issue, I have applied a patch to our branch 
that's ignore this new command.

https://bitbucket.org/riccardovangelisti/modemmanager/commits/2ef17b63ae0643b9c1f9134debe10c42495060e5

Note that ^CSCHANNELINFO seems to be not documented in any AT commands 
reference.

Regards,

Marco.
