Keeping Internet Calling available on 3g

[romanr9999]

I got internet calling working on my WM61 but after some inactivity time 3G connection is dropped and the phone stops refreshing the SIP registration, so I start missing calls.
Is there a way to make sure the phone re registers periodically with the SIP server and also keeps the connection active even if the phone is idle????

If i'm not mistaken there's a "disconnect when idle" option in Schap's Advanced Config.. try disabling this option.

Do you refer to the ¨GPRS disconnect¨ option??

Also, same question I asked originally applies to wifi connection. When I loose wifi signal internet calling is unavailable (of course), although once I get wifi connection again in another place Internet Calling does not become available. What I´m doing now to re-enable it is dissabling Internet Calling and re enabling it. I wonder if this could be done automatically.
