Registering different users with a FreeSwitch PBX. One of the users is not sending its VIA info. SIP Register is getting to FreeSwitch without the last hop info.

Anyone seen this before? Of all SjPhone users I configured for my colleges, this one is not working and I can't figure what the difference is. I can't spot the difference in what I set up amongst multiple users (OS not unique, same install, same profile configs). This one user can't register. Thx! A.C.
