[Spce-user] Rtp source address changes after in-dialog Invite

[Chris Hoffmann]

Hi Walter,

Thanks for your reply.

For reference here is my network.yml. I have my client subscriber
configured with 'rtp_interface' as 'ext'. I am unsure how to set a default
RTP interface?

hosts:
  self:
    dbnode: '1'
    ens192:
      ip: 192.168.x.x       | INT-ETH
      netmask: 255.255.255.0
      type:
      - ssh_ext
      - web_int
      - web_ext
      - rtp_int_ens192
      - sip_ext_incoming
    ens224:
      dns_nameservers:
      - 8.8.8.8
      gateway: xxx.242.37.xxx
      hwaddr: xx:xx:29:23:xx:xx
      ip: xxx.242.37.xxx      | EXT-ETH
      netmask: 255.255.255.240
      type:
      - web_ext
      - sip_ext
      - rtp_ext
    interfaces:
    - lo
    - ens224
    - ens192
    lo:
      cluster_sets:
      - default
      ip: 127.0.0.1
      netmask: 255.255.255.0
      shared_ip: []
      shared_v6ip: []
      type:
      - sip_int
      - ha_int
      - aux_ext
      - api_int
      - rtp_int
      - stor_int
      v6ip: ::1
      v6netmask: 128
    role:
    - proxy
    - lb
    - mgmt

Thanks for your time,

Chris
