Can FusionPBX do TCP for SIP messages for external calls? We are having a problem with one provider where some of our calls are failing, and root cause reveals it is due to lost UDP sip messages on the public network somewhere.

I confirmed that our system is doing TCP SIP invites for internal calls, but UDP for external calls. We would like to set TCP as the SIP transport, but I cannot find where this setting could be changed. Any information anyone can offer is greatly appreciated.
