             Summary: For WebRTC clients Asterisk insert same ip address in "source ip address" and "destination ip address" fields in HEP packets
                 Key: ASTERISK-26758
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26758
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_hep, Resources/res_hep_pjsip
    Affects Versions: 13.13.1
         Environment: Centos 7.3 (1611), HOMER 5.0.5, PJPROJECT 2.5.5
            Reporter: Max Norba
            Severity: Minor


For all SIP packets that generate my WebRTC clients Asterisk send in HEP packets same ip address (client ip address) in source and destination field. On call-flow in HOMER it looks like client send all SIP packets to himself. Some example from pcap trace:
{noformat}
HEP3 Protocol
HEP ID: HEP3
Length (Bytes): 1892
Protocol family: IPv4
Protocol ID: UDP
Source port: 49467
Destination port: 49467
Timestamp: 1485262590
Timestamp us: 903000
Protocol Type: SIP
Capture ID: 1234
Source IP address: 192.168.1.58
Destination IP address: 192.168.1.58
Correlation ID: 48607821-99d8-d400-4531-557e671ef1cf
{noformat}
For trunk connections, clients that use ip phones or softphones all work as expected. The problem only with clients that use websocket as transport.
