Can anyone comment if there is any added delay or degradation by going with the Simonics gateway solution vs connecting directly to Google xmpp by buying a obi200

The pedantic answer to your question is yes there is added delay. Delay can degrade the perceived quality of a service.
However in more detail:
1. Yes for both incoming and outgoing calls there is extra time before the called phone starts to ring. This is rarely a problem.
2. Yes for both incoming and outgoing audio, there is extra delay in the path. The actual amount is small and rarely a problem.
3. As both GV and your OBi use u-Law encoding of the audio there should be no requirement for the Simonics gateway to perform any transcoding. There should be no degradation of the audio signals.
The situation with incoming calls to you via the Simonics gateway is similar* to that of people who forward their incoming GV calls via another SIP provider eg Callcentric to their OBi. How many times have you seen adverse comments about the effects of that? The Simonics gateway adds a similar inverse arrangement for your outgoing calls.
(* The Simonics gateway introduces less unwanted effects than that.)
The answer you were probably hoping for is that there is no appreciable reduction in the overall user experience.
SteveInWA:
In the spirit of full disclosure, there's also:
4. There is an initial delay of 1-2 seconds after the called party answers, before they will hear your voice. This is a byproduct of how the gateway works with the XMPP service, AFAIK, and it does not continue throughout the call.
In general, for all types of digital telephony, delays of 250ms or less aren't enough to bother people. Delays longer than that tend to be annoying or disruptive to the brain trying to hold a conversation.

@ SteveinWA - regarding your response #10 I presume it was to my #9 reply - sorry if I wasn't clear - I'd already read those and was aware that its Google certificates and EOL of the 110 that are the problem. I was just wondering why it started working again - and has been up since - if the GV servers that I usually connect to (and I'm not sure how those get chosen) had already switched to new certs and my connections were timing out consistently for a few days, why it suddenly came back online. Somehow switched back to a server still using an old cert? Just technically speaking.
I'm assuming that eventually it will go offline again at some point.
Just asking anyone if they can come up with an explanation of why it went out for a few days and then came back and is still up.
thanks
