Is the UC540 capable of handling 2 SIP trunk connections to 2 different providers?  Thanks.

I have this problem too.

Awesome, thank you!

Does UC500 support multiple SIP trunks?

The  UC500 can have SIP trunks to different service providers which may be  required in some cases for least cost routing etc. This is an optional  Supplemental Feature that is not configured by CCA 2.2 but requires CLI  expertise. This feature is supported on the UC500 software pack 8.0.0 or  later - CLI configuration is at http://www.cisco.com/en/US/docs/ios/voice/sip/configuration/guide/sip_cg-multi-registrars.html .

I had a similar question to this.

Can I have two definitions (accounts) for the same ITSP (Engin) configured?

i.e. on a UC560 can I have two SIP trunks configured to Engin and route calls based on originating DN.

Before you ask why

I have multiple ISDN DID ranges for inbound calls.

My Engin SIP trunks are configured to SET the outbound caller-id to a particular number so return calls come back to reception. I need a second user group to caller-id with a different number when going outbound via SIP hence the second trunk.
