Fwding calls via SIP trunk

PRI → Cisco Call Manager → SIP Trunk → FreePBX -->Registered User|Phone
I created a pjsip trunk between my Cisco Call Manager and the FreePBX system. In FreePBX it shows the trunk up and it shows the User 7123 registered. Created a route pattern in Call Manager for 7123 to go FreePBX Gateway (SIP Trunk). From my cell, I dial XXX XXX 7123. The phone rings. I pick it up and on the cell I get “User Busy”. What am I missing?

Can you please post a call trace with pjsip debug enabled via pastebin?

For pjsip, it is called logger, not debug (pjsip set logger on).
