asterisk does not store the SIP packets, you can keep a packet dump running w/ wireshark

How to fetch SIP Packets from Asterisk

Posted:Wed 07 of Oct, 2009 (11:33 UTC)

We are using Asterisk-1.4. We have configured manager.conf file and connection with the AMI is successfull using username and password. We want to monitor/fetch SIP packets from TCP port. Please let us know how to take SIP data from tcp port.

Our scenario:

We are developing CTI applications where we need SIP data from PBX such as SourceIP,Username,Destination IP,TAG,VIA,Contact,CALL-ID,C-Sequence etc for each of the SIP packets such as REGISTER,BYE,INVITE,ACK,SUBSCRIBE,NOTIFY etc.

e.g Wrieshark displays SIP packets for activities going on SIP port in the below mentioned format:

o SIP Packet as displayed on wireshark*******************

SIP/2.0 200 OK
Via: SIP/2.0/UDP;branch=z9hG4bK10e203f8;rport=5060
Contact: <sip:1000000@>
To: <sip:1000@>;tag=1f0f342c
From: "Unknown"<sip:Unknown@>;tag=as4a585648
Call-ID: 38670a55c46d1235YzY2YWQxZTM0ODk4NTRhZDI5MjY3YjMyYjE4OTlhZjc.
CSeq: 102 NOTIFY
User-Agent: X-Lite release 1003l stamp 30942
Content-Length: 0

After receiving these SIP Packets from Asterisk,we can parse that data according to our requirements.
Is there any text/data file or database where asterisk stores all the information in above format?
If we need to fetch this data at realtime from the port than how can we do that?

Request for an early reply!!!
