When the 110's are sent to be used in places that don't have very good internet bandwidth, it would be nice to have a CODEC option (especially G729) as part of the menu selection for those that aren't very familiar with ATA parameters.
Several providers use *123 for voice mail. Having this on the menu pointing to the actual voice mail number would be helpful.
Also having the MWI voice mail light as an option would be a help.
I believe these options would eliminate a number of support queries.
FYI Vitelity OBiTalk setup selection:
The menu setup for vitelity sets the proxy server to
sip24.vitelity.net. My account registers with this proxy but can't make outgoing calls (Don't have incoming). The Vitelity setup wizard sets the proxy to
sip3.vitelity.net for ATA's. This works for my account.
