In testing with an old (1980's) phone plugged into the Cisco ATA122, everything works perfectly on a number of NZ corporate voicemail systems. All good.
But when I plug in my Philips 321 base-station & wireless satellites, I can dial calls, but I get zero recognition of numeric tones by any voicemail systems. Everything else works OK (eg: dialing the actual phone number) - just no tone recognition by any answering voicemail system.
Note that these Philips handsets & base station were in daily use before the transition to VOIP - so the tones on them have been 'working' for years. Now, however, they don't over the VOIP.
Maybe they don't make it beyond the SPA122 ? But then why do the tones from the 1980's phone succeed when I plug it in with no change to any settings ?
I'm finding this a hard issue to Google - so I'd be very grateful for any pointers.
It's also not a problem that works well with a phone helpline - for obvious reasons ;-)
I'm guessing there will be settings in the ATA122 (now running the standard 2Talk config file) which may be worth playing with ?
Note - I'm running v1-3-5 firmware in the SPA122 (as I think this was a bigger/known problem when this device came out).
