SIP devices should also take into account the provided TTL. I know that Mediatrix gateways accept the provided TTL with no problem. Hi Dave

I have setup this configuration and I'm in the process of testing it more thoroughly. My greatest concern is that some devices/applications may not honor the TTL, or maybe their DNS is provided by a ISP that does not strictly honor TTLs. Have you seen any problems related to this?
