Outbound CID в многоканальном транке

Добрый день. Имеется такой вопрос: Есть многоканальный транк подайющий по sip(на н число внешних номеров), при исходящем звонке передается транковый Outbound CID. Если же к каждому екстеншену прописать свой внешний Outbound CID, то при звонке все линии заняты.

Надо же что бы некоторые екстеншены имели свой внешний callerid. Или может есть какой то другой способ в многоканальном транке передачи исходящего callerid ?
