Hi,
After a few changes to the firewall MiCollab is working, PC Client registers and Softphone is able to make/receive calls, all this as Teleworkers using MBG on the DMZ.
However, it does not work when remote users have their corporate VPN up. Note they are using Fortigate SSL VPN with Split Tunnel (i.e. only traffic over the VPN is traffic to corporate resources, rest of Web traffic goes out locally from everyone's home router), and the other thing is they use corporate DNS server while VPN is up.
Having corporate DNS forces that all micollab, mbg and mivb FQDNs are resolved locally to the local IP addresses.
When having the VPN up MiCollab PC Client registers and it can start a call, user listens to ringback. But when call is answered at the other end it does not establish. User keeps listening to ringback and far end hears nothing.
It's like the signal back is not able to reach the PC Softphone within MiCollab Client. Most likely signal and media are using one route but return signal is using differnet path.
Have you come across this scenario in the past? any hint to resolve this?
Firewall Policies are according to MBG Eng. Guidelines. And as I said before, everything works fine when as pure teleworkers using MBG, without VPN.
Cheers,
daniel
