Since I've upgraded from the ASA5505 to the ASA5516-X, my Voip adapter no longer works. It worked fine with my old ASA5505 but not since I've upgraded.
My VOIP adapter is a SPA122 from Cisco. It's communicating via UDP on port 5060. The settings on the SPA include "Nat mapping enable - yes, nat keep alive enable - yes".
The problem now is that my phone calls all last EXACTLY 20 seconds. After this, the call just drops cold. I checked the logs on the ASA and I can't see any messages about blocking or anything else.
I have checked the default inspection rules and SIP is listed there and enabled for UDP and TCP.
Please let me know what can be the problem here.
Thanks.
