Registration refresh time - interval change

[Elysium]

Is there a way to change the interval (in seconds) of the Registration refresh time? For one single line not for all lines?
I'm asking because one of the VoIP providers that I look at needs to have it at every 60 seconds otherwise they block your account and MAC.

I see it must be Time between registration attempts (in seconds) under Registration settings. I hope I'm right

Now the question is. How's that this value can only be set when you create a new VOIP provider but you can not change it later? (I'm using the 3CX Phone System Version5.1.4128.0)

The "Time between registration attempts (in seconds)" can be changed under the gateway setup for that line.
