Adding new ring types

Adding new Ring types according to yealink configuration parameters V80

[bmachens]

We already have "yealink_ring_type", so why we need to have a duplicate?

Adding Silent, Splash and Common to "yealink_ring_type" should be enough or not?

[yozmag]

There is account.X.ringtone.ring_type and phone_setting.ring_type the difference between the two is the 'Common' that is only used in account.X.ringtone.ring_type. Looks better to have have two types. What is you idea about this issue.

[bmachens]

Yes, now i see the "Common" problem. Make sense to have these two types.
I toke a look at the Provisioning Guide and may we add Silent and Splash to "yealink_ring_type" so we would have the same config in web UI and phone UI

[yozmag]

Yes, we have to add those, I missed that. Do you do that or I do the change?

[bmachens]

Feel free to do that. it's your PR

[yozmag]

I have changed the PR. It all ok now.
