Problem receiving MO Meta-Data (TLV) values from sms-service

Dear All,

I built the cvs-20081021 that includes meta-data code to test it.

In bearerbox configuration I included the following to receive MO TLV 
0x0204 (defined optional parameter)
group = smpp-tlv
name = "user_message_reference"
tag = 0x0204
length = 2
type = integer

The deliver_sm PDU sent by the SMSC contains at the end the following 
bytes 0204 0002 00a7
and and bearerbox logs the TLV:
DEBUG: Optional parameter tag (0x0204)
DEBUG: Optional parameter length read as 2
DEBUG:   user_message_reference: 167 = 0x000000a7

Smsbox configuration is:
group = sms-service
keyword = default
get-url = 
"http://myserver/kannel.aspx?sms_source=%p&sms_dest=%P&smsc-id=%i&sms_command=%k&sms_params=%s%r&sms_text=%a&carrier=mts&meta_data=%D 
<http://myserver/kannel.aspx?sms_source=%p&sms_dest=%P&smsc-id=%i&sms_command=%k&sms_params=%s%r&sms_text=%a&carrier=mts&meta_data=%D>"

However the TLV value is lost when submiting the MO to our endpoint

Any ideas on this?
