I have 3 3cx pbx's linked via bridges.

Up until V10 it was possible for phones on each pbx to have function keys programmed for BLF for extensions on the other pbx's eg:

Phone Id = 100@192.168.0.1
BLF : 200@192.168.1.1

Now an error occurs in the log as follows:
20:58:11.447 [CM102001]: Authentication failed for SipReq: SUBSCRIBE 200@192.168.1.1:5060 tid=-jtrso8xq65qn cseq=SUBSCRIBE contact=100@192.168.0.1:2052 / 6 from(wire); Reason: Credentials don't match, check that authorization-ID and password match the ones in extension settings

I assume that this is due to the improved anti hacking system in V10, but is there a way around this?
