Hello colleagues! I’m trying to resolve a little problem with NAT and SIP ALG. In particular, I’ve made an IPIP tunnel with IPSEC to my corporate router(cisco) and configured NAT in order to hide my home network. However, I’m also using Cisco jabber client, which does not work right. For instance, even though with enabled SIP ALG feature, the router does not change VIA and CONTACT fields in SIP messages. So is there a way to overcome this issue ? I’ve tried netmap and masquerade nat.
