Transmit Video(h263) between Two Asterisk Using IAX trunk

I want to send video calls of one asterisk A two another asterisk B .

My architecture is as bellow:


I m using following example to connect two asterisk.

I m using IAX to connect two Asterisk.±+dual+servers

I m using Xten Eyebeam as Video Phone

Currnetly Asteriksk A crashs when User Of Asterisk B starts transmitting Video.

Through Debugging i found out that IAX does transmit the video frame to Asteriks A but
Asteriks A is not able to write Video Frame to SIP channel and it gets crashed…

Does Any One Have Idea aboute this issue…

Please Help
