SIPREC Sample Wireshark Traces

Please find sample wireshark traces attached for SIPREC between a communication session on a Net-Net SBC and the Interactive Session Recorder from Acme Packet.  Attached are 4 traces:

 

• '111 calls 333.pcap' (SIPREC Invite = packet 14)
• '333 calls 111 - session recording required enabled.pcap' (SIPREC Invite = packet 17)
• 'Failed call.pcap' -  call from 333 to 111, but 111 is busy (SIPREC Invite = packet 4)

Notable hosts from traces:

• Extension 111= 172.18.1.10
• Extension 333 = 172.18.1.12
• APKT SBC (Comm. Sessions) = 172.18.1.44
• APKT SBC (Recording Session) = 172.18.2.119
• APKT ISR  #1 = 172.18.2.120
