[VoiceOps] Delay on RTP for Inbound Calls

[Ujjval Karihaloo]

Yes, it can be reproduced from landlines as well. I will try to get a trace from LandLIne and check out the RTP playback.

Does this ever happen if Party A is using a land line?

Is it always the same cell phone carrier?

I found it interesting that you mentioned a cell phone for party A so that is why I am asking. Maybe it is just me but I do not really consider some cell carriers to be that reliable. Awkward starts in conversation in the first few seconds of a cell call, cell phones being called but never ring even with good signal yet caller hears ringing, etc...

Maybe it is not the VOIP part but a cell carrier issue? Do any other parts of the call conversation have delay/lag/lost bits of conversation?
