[Freeswitch-users] Occasional INCOMPATIBLE_DESTINATION error

Mon Jun 22 22:50:14 MSD 2015

OK, thanks.  Since this is not reproducible at will, the only way for me to
try it with sip.js is to release sip.js into production.  It's not really
feasible just to test this one case.

created by Chrome and not manipulated by the library.

I think the question is this:  Is 0 a valid value for an attribute ID.
Unless it's explicitly forbidden by some RFP, I don't see why it wouldn't
be.  If it is, then shouldn't FS handle it?
