Choose phone if no phone defined for message
Phones are choosen using type, priority and remaining volume :
1 - If sms is a mms, try to use mms phone if any available. If mms phone available use mms phone, else use default.
2 - In group of phones, keep only phones with remaining volume. If no phones with remaining volume, keep all.
3 - Groupe keeped phones by priority get group with biggest priority.
4 - Get a random phone in this group.
5 - If their is no phone matching, keep phone at null so sender will directly mark it as failed
