International Calls not working from External PBX Span 2 inbound and routed back out on Span 1 towards PSTN

I have a PBX tied to ZAP/g1 and have a 011. in the outbound route.
Routing is working fine, but for some reason when I look at the console, I find that the 011 is getting cut off only on external calls.
Internal SIP calls work fine.
From external PBX (not working - notice 011 is missing)
– Executing [420222710774@from-internal:2] Set(“Zap/46-1”, “_NODEST=”) in new stack
Sip call (working)
– Executing [011420222710774@from-internal:1]
– Executing [011420222710774@from-internal:1] Set(“SIP/70278441234-08faccf8”, “CALLERID(num)=7027841234”) in new stack
– Executing [011420222710774@from-internal:2] Dial(“SIP/7027841234-08faccf8”, “Zap/g0/011420222710774”)
So somehow the 011 is getting stripped.
I did a bypass and attached the external PBX directly to the PRI and the calls go through just fine, so I know it is not an issue with the PBX.
Is there a way to monitor from the console or review of a file what asterisk sees on the inbound from the external PBX just to be sure?
I presume the above executing display is in fact just what is being processed not necessarily the decoded input on Span 2.

Thanks for your help!!
