Wifi Calling with Google Pixel- breaks up connection- not workable-

[iknoian1]

I have a Google Pixel II phone which uses wifi  for voice calling.  It works very well everywhere except at my house. I connect to a call with wifi via my home xfinity service.  I hear the caller  I am speaking to on my phone well.  But shortly after the call begins, the person I am talking to says my voice breaks up and they cannot understand me. 

I just upgraded my Xfinity modem/wifi router service with the faster system provided by Xfinity and new xfinity equipment.  The problem remains exactly the same with the new and previous equiptment.

Looking for ideas for a solution?

If it is not a phone approved or sold by XM then all bets are off as to what will work . PS.. I need to read closer, this post was about Xfinity and not XM on  the XM forum.

root-causes which seem consistent with the issue include older/buggy codecs and or buggy phone app software.    it is pretty hard to make codec use two different voice channels without glitching.    possible ways to workaround/avoid the issue:    1.    go airplane mode, enable wifi, make the call.      2.   turn off wifi, make the call.    3.   disable wifi-calling entirely.       btw, have you enabled VOLTE or "hd calling"?    "HD" audio or "VoLTE" is outstanding end-to-end, arguably better audio quality than wifi-calling and likely with lower latency too.

TTFN!
