NOTE: Calls dropping/disconnecting after a very lengthy time (few hours) are due to normal limits within any telephony system. TBB has a three hour limit for all calls.

You may sometimes encounter a situation where you are able to place a call and start a conversation, only to have your call drop/disconnect suddenly. This can occur after one second, 40 seconds, or fifteen minutes or more into a call.

Please first ensure that you do not have a CABLE or DSL modem resync issue due to low signal (SNR), or noise - an unstable ISP connection.

•With DSL, a symptom is that your IP address might change often. See your modem stats, or call your ISP, to see if you keep losing either the DSL or PPPoE connection when your phone call dies. If so, this is not a TBB problem. DSL resync problems can sometimes be alleviated by having the Speed profile reduced on your line. Your modem may be too far from the DSLAM (Telco CO) to have a good signal at a high speed - it might be OK at 1,5Meg but terrible at 3.0Meg.

•With Cable, you also need to verify that the connection is not being temporarily dropped. If so, a possible solution may involve adding a signal amplifier to your line. You will need to call your ISP to determine how to verify this.

In either case, you might sometimes be able to "flash" the call to get it back - but not always.

If you determine that your ISP connection is stable, refer to:

•Call drops/disconnects after 5 minutes - Bell Sympatico SS5200 modem/router?
or
•Issues when the ATA is behind (certain) routers
or
•Issues with SHAW CABLE
