Let me start by saying, I'm not a Vodavi tech, but seeking some wisdom from the group.
We have a customer with a Vodavi XTS-IP. They have five locations. Four of the locations have Inter-Tel systems networked (Axxess and 5200's), the fifth location has the Vodavi. We installed four Inter-tel IP SLA units at that location and connected the single line exts to trunk positions on the Vodavi.
Here is the trouble, when someone from any of the Inter-Tel systems dials the hunt group for the IP single lines, voice mail on the Vodavi answers the call, they dial an extension and if the person doesn't answer, when that call forwards to voice mail on the Vodavi, the caller then hangs up. The IP SLA doesn't release from the voice mail and it ties up the single line exts and the voicemail port. The Inter-Tel system then gets an off hook alarm for the IP single line ext. The ports do free up, but it takes about 5 minutes. We have no settings on the Inter-tel switch to adjust for disconnect.
Any suggestions as to tweaks to the Vodavi that would assist with actually dropping the call when the caller hangs up?
