asterisk users - Feb 2008 - ExtenSpy strange behavior on Asterisk 1.4.18

Hi list,

I have been experiencing a strange behavior with asterisk and i would 
like to know if someone else has face it.

This is my scenario,

3 extensions created on sip.conf: 121 | 123 | 123

Everything work just perfect except for the following issue:

I have this block on my extensions.conf

[record] ;-------Extensiones individuales
exten => _7781[23]X,1,Authenticate(/etc/asterisk/eavepass|am)            
   ; Authenticate
exten => 
_7781[23]X,n,extenspy(${EXTEN:3:6}@${CONTEXT}|bqr(${EXTEN:3:6}-))  ; 
extenspy(exten at context|bqr(fileprefix-)
exten => _7781[23]X,n,Hangup                                             
   ; Hangup


If 122 calls 123 , and 123 answers ( 122 =====[called]====> 123 ):
- Dialing 778*122* from 121 (for spying and recording) generates a 0 
byte file like 122-.1203025287.raw (on /var/spool/asterisk/monitor/)
- Dialing 778*123* from 121 (for spying and recording) generates a 
byte-significant file like 123-.1203025598.raw

If 123 calls 122 , and 122 answers ( 123 =====[called]====> 122 ):
- Dialing 778*122* from 121 (for spying and recording) generates a 
byte-significant file like 122-.1203025808.raw
- Dialing 778*123* from 121 (for spying and recording) generates a 0 
byte file like 123-.1203025923.raw

In the situation where the 0 byte file is generated, NO AUDIO is 
listened on 121; I have NO IDEA of what could be causing this, as 
there's no apprently refference on the documentation. Could this be a 
possible bug?


Regards,
