Call waiting problems - extra noises

[bretski]

Update: I've been playing with settings, and have determined that the extra tones ARE being caused by the CWCID. One of the PAP2T's settings allows you to turn off the call waiting caller id. Doing so makes the extra tones go away. The downside is obvious: no caller id for call waiting. :/

So...there's gotta be something that can be done server-side to fix this, right?...right

Not sure if that's a correct assumption. Say your car is running ruff because you put cheap gas in it. All of a sudden it stops running bad when you put good gas in it, obviously not the cars fault. Just because you turn off the CWCID and it stops, doesn't necessarily mean it's the TA. It just passes the info that's sent to it.

But hey, I could be waaaaaay off

I agree, it's not necessarily the ATA's fault. My point was: the extra tones are the CAS, SAS, ACK associated with CWCID.

...and, I never had this problem with POTS using these exact same phones. VoIP is the x-factor, and the ATA is a logical suspect (but not the only suspect, obviously).

Something I just found in a firmware release notes document for another Linksys device (resolved issues):

"CIDCW Ac digit (A or D) is sent out-of-band if the DTMF Tx Method is INFO. The symptom is that the other party may hear the ACK digit if the peer device plays out-of-band DTMF digits via a SIP INFO message"
