Hi all,
My scenario is as follows:
I have All the CSCFs on the same IP using different ports.
P-CSCF advertises a public IP. Rest of the nodes including I-CSCF and
S-CSCF listen local only.
Behavior: When an ACK or PRACK goes from P-CSCF to S-CSCF, the RURI changes
such that alias parameter is removed.
Hence, P-CSCF ends up sending PRACK and ACK on private IP of UE.
Here's what the config looks like:
listen=udp:lo.ca.l.ip:6000 advertise pu.bl.ic.ip:6000
alias=pcscf-ims.domain.net
#!define WITH_NAT
Any hints?
