Re: [OpenSIPStack] [OpenSBC] Call through Sip Trunk if Enum fails

[Joegen E. B. <joe...@gm...>]

You would probably be able to reach at least up to enum, osbc...  But 
you might not be able to failover to a sip-trunk right now because the 
SIP-Trunk is handled differently than any other route.   I am not very 
sure.  Have you tried

[sip:*] enum:nu...@e1..., sip:numkber@osbc2, 
sip:number@your_itsp;sip-trunk=true

?
