Can you manage one SP using the web portal, and the other 3 using Obitalk?
Yesterday, Vestalink started using the failover # for my inbound calls
I rebooted my Obi, then I did ***81
Now the URI field is missing in Obitalk.com
If I select Vestalink as a provider, URI field is missing
If I select generic, sometimes the URI filed shows up, then after I enter all the info, and go back in, it is gone
If I click on my IPCOMMS SP the URI field is there (but no entry)
I defined GV on SP1 via OBiTalk then switched to the Web portal.
See: http://www.obitalk.com/forum/index.php?topic=8685.0
Edit:
If you want to define a trunk via Web portal then switch to OBiTalk, do steps 5-7.
