[Serusers] Sip Method problem

[yy]

Hi guys,

I've noticed that my sip methods are not decoded and are stored as 
integers in mysql database. For instance,

Acct-Status-Type = Start
       Service-Type = Sip-Session
       Sip-Response-Code = 200
       Sip-Method = 1 <-------------------------------------------- Here
       User-Name = "2001 at orion.lab.test.com"
       Calling-Station-Id = "sip:1001 at orion.lab.test.com"
       Called-Station-Id = "sip:91711 at orion.lab.test.com"
       Sip-Translated-Req-ID = "sip:91711 at 192.168.1.1:5060"
       Acct-Session-Id = "000ded22-eeb200af-7abf52ea-7594628f at 192.168.4.2"
       Sip-To-Tag = "19C6CC30-4E3"
       Sip-From-Tag = "000ded22eeb200127e7c3590-329e270c"
       Sip-Cseq = "102"
       NAS-IP-Address = 192.168.1.2
       NAS-Port = 5060
       Acct-Delay-Time = 0
       Client-IP-Address = 127.0.0.1
       Acct-Unique-Session-Id = "fb24188f75e8946d"
       Realm = "orion.lab.test.com"
       Timestamp = 1113208054

Am I missing something, such as missing entries in my dictionary? How 
can I make it convert the code into the actual text representing the sip 
method, such as INVITE?

Kindly advise,


Regards,
