The Court does have the power to make an Order in the absence of the Other party if there is a reason for his or her absence and the Court considers it right to do so.
I understand your frustration that even in his absence he was "listened to" but the Order that has been made relates to minimal contact which is why the Court were prepared to make it despite his non appearance.
The law says that children are entitled to contact with both parents - and this represents a way of achieving this whilst keeping you and your child safe
He will have considerable difficulty in getting any more contact in the foreseeable future (on average the next 12 months) given his failure to attend on this occasion - unless of course he can prove that it was impossible for him to attend
I appreciate that this is not what you wish to hear (and I apologise for the connection problems) - but there is nothing you can do about the Order.
If you decided to appeal it ( a possibility) there is always the chance that he might attend the hearing and get more contact than the minimal Order that was made.
As it is it is unlikely that he will keep up with the letters for more than a month or two - just make sure that you keep them all - and send the snaps via recorded delivery/email
Please ask if you need further details
