Hi.
From the lack of response to my question, I'm assuming that either:
a) putting a call on hold is not possible via AMI
or
b) everyone thinks it's so obvious that I should be able to see it for
myself
Can anyone confirm one way or the other?
If it simply isn't possible, I'd like to put my efforts into exploring
alternative solutions instead of spending more time on AMI.
Thanks,
Antony.
