Providers don't have any issues with caller id's. We can even call from a single digit. And even if a sip account is not associated with a caller id (a number) rather its just a name (as skype id like xxx.yyy) when initiated a pstn call, the providers use local numbers (if ur gateway is in germany then the proivder will use a germany number) to call and the receiver will that local number.

Hello,
It's just a guess, but I think most SIP providers aren't going to like the all-zeroes Caller ID/ANI that you're sending here:
Contact: sip:0000000000@1.22.216.96:35465;transport=UDP
This is especially true since their routing is influenced by CLID, due to the possibility of intra/inter-jurisdictional rate differences.
