How solve these errors

I have asterisk 1.4, I can’t external call by analog phone connected on Zap/2 channel using OOH323. In H323 log file there is :

ERROR: UserInfo encoding failed
10:51:13:225 Error:Failed to encode uuie. (outgoing, ooh323c_o_1)
10:51:13:225 Error:Failed to encode H225 message. (outgoing, ooh323c_o_1)
10:51:13:225 Error:Failed to enqueue SETUP message to outbound queue. (outgoing, ooh323c_o_1)

What I can do ?
