There is a known issue with sip calls to
user@pbxes.org not going through...
The main reason I am aware is that PBXes does not expect incoming calls to
user@pbxes.org (it wasn't built that way)...
Attempting calls to
user-123@pbxes.org also fails unless you mannage to set up dummy trunks and the appropriate inbound rules to deliver calls.
My understanding is that issues with SIP Calls to pbxes.org are not VoXalot specific issues...but rather a general issue with all providers attempting incoming SIP Calls to PBXes...(try calling the same SIP URI from CallCentric for example).
As far as VoXalot and SipBroker ENum routing:
-To test VoXalot ENum routing (having enabled ENum under Smart Call/Dial Plans, use the test line to enter the number with an ENum record you wish to call... it should tell you how it is treating it).
