Matt Jordan commented on ASTERISK-20234:
----------------------------------------

Hm... I noticed on the SNOM forum that you can configure this properly in the phone.  I'm not sure yet if we want to make Asterisk actually ignore the fact the SAVP wasn't specified, since doing so is technically non-RFC compliant behavior, and there is a workaround available in the phone.

Just letting you know that this patch may not get committed in the form that its in, so you may want to configure the phones as opposed to relying on this behavioral change.
