Can't Get Call Waiting to Work on Vonage Line Connected to LINE Port
Glenk:
I have an OBI110 with Google Voice on SP-1 and a Vonage adapter on the LINE port. The LINE port (Vonage) is used for inbound calls and SP-1 (Google Voice) is used for outbound calls. If a call is received on the LINE port and is answered then a second call comes in, I hear the call waiting beep but when I attempt to answer the second call, I get the SP-1 dial tone and can't connect to the 2nd call. It acts like I am attempting a 3 way call between my phone, the 1st person on the Vonage line and a call to be made on the SP-1 line.
In standalone operation of the Vonage connection (no OBI110), when a call is placed on hold by hookflashing, the word "HOLD" appears next to that caller's number on the Vonage adapter's display. The display will alternate between the info for the 2 callers (caller ID name & number, number of minutes the connection has been active). With the OBI110 connected, neither call has the "HOLD" indicator next to the number.
I opened an Obi support case and they suggested performing a double hookflash. That produces the same result as a single hookflash by presenting the SP-1 dial tone. Subsequent hookflashes will toggle the phone connection between the LINE port and SP-1.
I've tried setting the phone port to "Send hook flash to PSTN". That results in the HOLD indicator on the Vonage adapter for the 1st call but still no voice connection to the 2nd caller. I get a hum on the 2nd caller’s line but no voice connection. The 2nd caller hears low level noise but no voice. I am unable to flashhook back over to the 1st caller, that call is stuck on hold.
The Software version is 1.3.0 (Build: 2690)
Any suggestions would be appreciated.
Stewart:
I believe that some electrical property of the Vonage device is confusing the OBi and adjusting one or more Line Port parameters may fix it.
Please look at System Status, PHONE and LINE Port Status and report the values of TipRingVoltage and LoopCurrent under Line Port Status in these three cases:
1. With the system idle (Vonage line on-hook).
2. While an incoming call is in progress.
3. After call waiting beep and a hook flash has been sent (Send hook flash to PSTN is on and Vonage box HOLD indicator is on).
Glenk:
Thanks for your assistance Stewart. Below are the statuses that you requested.
1. With the system idle (Vonage line on-hook).
Phone Port Loop Current: 0 mA, Line Port Loop Current: 0 mA
Phone Port TipRingVoltage: 45 V, Line Port TipRingVoltage: -50 V
2. While an incoming call is in progress.
Phone Port Loop Current: 20 mA, Line Port Loop Current: 26 mA
Phone Port TipRingVoltage: 7 V, Line Port TipRingVoltage: -6 V
3. After call waiting beep and a hook flash has been sent (Send hook flash to PSTN is on and Vonage box HOLD indicator is on).
Phone Port Loop Current: 20 mA, Line Port Loop Current: 26 mA
Phone Port TipRingVoltage: 7 V, Line Port TipRingVoltage: -6 V
Stewart:
I'm very surprised -- the loop voltage and current are completely normal.
The next questions are which side is not passing the audio and why. Connect a test phone on the line side of the OBi, preferably a line-powered corded one. For example, using a splitter, connect both the OBi Line port and the test phone to the Vonage adapter. Then, when you get into the problematic state, pick up the test phone and report whether it can hear and talk to the OBi user, and whether it can hear and talk to the the second incoming caller. Does the OBi Call Status show anything strange at this time?
Also, do other Vonage hook flash functions work, e.g. can you establish a three-way call on Vonage through the OBi? (Check the OBi's Call Status and/or your Vonage log to confirm that both legs are really on Vonage.)

Glenk,
The call waiting tone comes from the Vonage adapter. Any chance the OBi is interpreting that tone as a disconnect tone?
In addition to following Stewart's suggestions, I would run a debug syslog on the OBi to see if that data gives any clue as to what is happening.
I did a call waiting test with a Linksys ata attached to my OBi110 line port. It worked as it should with a single flash from the phone attached to the OBi. I had "Send Hook Flash to PSTN" set on the Phone Port.
