VOIP Analog Telephone Adapters – Dial Plans
May 7, 2014
Picked myself up a Cisco SPA112 to replace the wonky built-in VOIP capability of my router. However, I seem to have some unusual behaviour. Namely, when I take my cordless phone off the hook, I only get about 4 seconds to start entering numbers before the ATA switches over to the “off hook alarm” mode and rejects any further digits. Unfortunately, the phone’s built-in dialer waits a few seconds before starting to dial, so it’s pretty random whether you can dial or not.
