We have implemented a few VG224 in an Hotel environment and have experienced the following issue :
At times, no tones are heard on some analog phones.
The show stcapp device summary shows that the concerned voice port is in VMWI_DSP_SETUP calling state.
A shut / no shut resolves the issue.
We would like to know what could cause the calling state stuck in VMWI_DSP_SETUP and how to fix it permanently.
