             Summary: PJSIP advertise one floating IP address but RTP uses non-floating IP address
                 Key: ASTERISK-25632
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25632
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_pjsip
    Affects Versions: 13.6.0
         Environment: Centos 7
            Reporter: Olivier Krief


Setup is a cluster of two Asterisk boxes. Each box has several Ethernet interfaces and both share a set of floating IP addresses (pacemaker/corosync).

One box is volontarily powered off.
The remaining box send an outbound call to a PJSIP trunk.
Within SDP portion of INVITE message, I can read:
IN IP4 10.20.143.100
where 10.20.143.100 is a floating IP.
The INVITE message itself also comes from 10.20.143.100

A bit later, as captured with tcpcump, I can see outbound RTP is sent from 
10.20.143.101 (non-floating IP).

Trunk's transport is configured with:
external_media_address     : 10.20.143.100

I must add I'm new to clusters.

My question is:
is this feature supported (use of floating IP addresses)

Regards
