[cisco-voip] RedSky SIP Trunk

[Anthony Holloway]

Oh, good to hear!

Yeah NAT and SIP doesn't work without an ALG....well....sort of.  You could
apply a Lua script to the SIP trunk to modify OUTBOUND INVITEs,
effectively doing your own SIP inspection, but then it would apply to all
CUCMs, and you'd need it to apply to only that one.  Which you should be
able to do, but would require some reconfiguration of your SIP trunks, call
routing and callmanager groups.

Post back if you find a solution, or if you're still looking for help.
