The following items should be noted in relation to this Interop - – these are either limitations, untested elements or useful information pertaining to the Interoperability.

  • Short Code calls are not supported on Google Voice clients.
  • After an SBC switchover, the SBC takes around 45 approximately 12-16 seconds to establish a new TCP socket connection with GV for sending first SIP OPTIONS (with OPTIONS "pathcheck" profile interval set to 10 seconds) over TLS.  HenceHence, all the calls, including in-dialog messages initiated from GV the Google Voice end towards PSTN during this period, will be failed as fail because GV does not initiate any new socket sockets for a TLS connection , unless a new call/In-dialog request from PSTN end is initiated towards GV over TLS. 

These issues will be addressed by GV/Ribbon in their upcoming releases.
