SIP trunk, CUBE and CUCM 7.1.2

[John Cheetley]

Hi Cisco Techs,

Please let me know if posted in wrong forum

ISP supplied router has necessary details under VOIP and SIP tabs to connect to them for VOIP calls.

Do I need to configure CUBE as part of CUCM 7.1.2 to connect calls then?

Thanks again..

John,

you dont necissarily need a cube. if your ISP provide router supports SIP, you should be able to point your cucm trunk to that. there is no requirement from cisco that a cucm sip trunk needs to point to a CUBE, it could also point to a non-cisco product.  I hope that answers your question
