Mera и presentation indicator

Появилась проблема с использованием меры. При передаче сигнального трафика по h323 мера вырезает поле presentation indicator из calling party number Q931. С использованием параметра presentation в мере, это значение подставляется в h225 facility сетап пакета. Провайдер просит посылать ему поле presentation indicator в Q931. Как это можно сделать?

 

На меру приходит так:

 

Q.931
   Protocol discriminator: Q.931
   Call reference value length: 2
   Call reference flag: Message sent from originating side
   Call reference value: 003a
   Message type: SETUP (0x05)
   Calling party number: 'xxx'
       Information element: Calling party number
       Length: 13
       .... 0001 = Numbering plan: E.164 ISDN/telephony numbering (0x01)
       .010 .... = Number type: National number (0x02)
       0... .... = Extension indicator: information continues through the next octet
       .... ..11 = Screening indicator: Network-provided (0x03)
       .00. .... = Presentation indicator: Presentation allowed (0x00)
       1... .... = Extension indicator: last octet
       Calling party number digits: xxx
       E.164 Calling party number digits: xxx

 

C нее же уходит в таком формате:

Q.931
   Protocol discriminator: Q.931
   Call reference value length: 2
   Call reference flag: Message sent from originating side
   Call reference value: 0042
   Message type: SETUP (0x05)
   Calling party number: 'xxx'
       Information element: Calling party number
       Length: 12
       .... 0000 = Numbering plan: Unknown (0x00)
       .000 .... = Number type: Unknown (0x00)
       1... .... = Extension indicator: last octet
       Calling party number digits: xxx

Не понял что такое "Mera" в данном случае...

Например, в MVTS 3.1.4 есть параметр presentation_screening_allowed=1 для user.cfg и gateway.cfg.
