Cisco 2821 и x-lite: не реагирует на ответ в софтфоне.

Сделана небольшая АТС из циски.

Для теста прописываю:

 

dial-peer voice 8 voip

description x-lite bug test

destination-pattern ^5001$

voice-class codec 1

session protocol sipv2

session target ipv4:комп с xlite x.x.x.59:7374

session transport udp

no vad

 

Звоню с любого другого voip диалпира на 5001, софтфон звонит. Нажимаю ответ. В сторону циски уходит

Циска отвечает

Content-Length: 0

 

Но в сторону звонящего 200 Ok не отсылает, звонящий продолжает слышать кпв.

 

С другими софтфонами/шлюзами на месте x-lite все работает.

debug ccsip тоже никаких ошибок не пишет.

 

Чем ответ x-lite может не устраивать циску?

5008                -                 cisco              -            5001 (Xlite)
      > INVITE 5001, with sdp
         < 100                                     > INVITE 5001, with sdp
                                                   < 100 
                                                   < 180 
         < 180
                                                   < 200, with sdp   
                                                   > ACK

И тишина, rtp трафик в сторону циски льется, обратно ничего нет, 5008 слышит кпв.

 

Если вместо x-lite любой другой телефон, то:

5008                -                 cisco              -            5001
      > INVITE 5001, with sdp
         < 100                                     > INVITE 5001, with sdp
                                                   < 100 
                                                   < 180 
         < 180
                                                   < 200, with sdp   
         < 200, with sdp                           > ACK   
         > ACK
