[Solution found for the following puzzlement. Un-allocating or deleting in the local OBi100 box and in OBiTALK SP 1 setup and returning the settings to OBiTALK pre-configuration and starting from scratch with Anveo's setup tool called "OBi 110"]
Below, the original issue that is now moot.
-----------------------------------------------------
Anveo Basic install to SP1 seems to have not removed VestaLink
sms.intelafone.com is ProxyServer and RegestrarServer.
xxxx(acct number?)xxx@sip.anveo.com:5010
The VestaLink phone number comes up as callerID, not Anveo's.
Anveo has a guide for Generic setup. But, also seems to partly install from a strangely worded web page under their logo associated with OBi web page. [Caused, it now appears by an only partly un-allocated SP 1]
