I already saw some other posts regarding this… but just wanted to check for a last time :):
Can anyone think of a negative side effect of having all extensions register via TCP, instead of UDP? (I know the actual RTP will still use UDP)
We notice that it fixes nearly all our “UNREACHABLE issues” of people working from home with a crappy local network.
About the only negative I’ve seen expressed is that it slightly increases IP traffic, but a slight increase in traffic that’s already minimal is a pretty small price to pay. It’s possible that the SIP stack in the client might work better as UDP instead of TCP, but your own testing should reveal if that’s the case.
