Fr-Soltanzadeh created an issue (kamailio/kamailio#4164)

Description

In a IMS lab using Kamailio PCSCF, ICSCF and SCSCF default configs, I have used TOPOH module in PCSCF for topology hiding. Topoh config is as follows:

modparam("topoh", "mask_key", "my-key")
modparam("topoh", "mask_ip", "127.0.0.2")
modparam("topoh", "sanity_checks", 1)

As shown in attached traffic, SCSCF IP is not hided in 180 ringing and 200ok messages to the caller. In invite, ack and bye messages hiding is performed well.
