This one has me stumped.
Os7200 mcp 4.46d, mgi16 1.26

Trying to get 8 x smt-i5220 working locally, but getting garbled speech on ip to tdm (pri, digital handset)
Ip phone to ip phone is fine. Digital phone to spnet is fine.
Smt phones are 2.31 firmware

Any ideas?

1 more piece of info the display on the smt handsets shows a padlock icon when making a call (regardless of call type).
Ask phones have been set to both g711 and g729
