Private Networking CIDR on Kubernetes - local hostports undefined

[Catharsis68]

drachtio-server: 0.8.26-rc4
Version: 0.9.2

we are currently running the tag 0.9.2 on a Kubernetes environment.

Reproduce:

1. Set a CIDR that should be considered as private network via webapp: Settings > Admin > Private Network CIDR 5.56.247.42/32
2. Create a Carrier with that IP as SIP Gateway for incoming traffic
3. Send a request from that IP e.g via SIPp

Expected:

1. sbc-inbound has access to localHostports from srf
2. Private IPs are negotiated in the PCAP Contact header

• Contact: sip:10.1.206.25:5060;transport=udp

Actual:

• Contact: sip:undefined;transport=udp

200 OK (INVITE)

Update: we have updated the drachtio-server to 0.8.27-rc1

The contact header is no-longer undefined but still the public IP is advertised in the Contact header
