UC560 showing no dsp on FXO ports when making a call.

Hi Everyone,

We are having 2 customers who are facing this problem on 2 differenct model one is UC560 and another one is UC540.

This is happening with almost all the ports that when ever we are making a call the voice ports hangs showing no dsp and it hangs in that state until we

issue the shut & no shut the ports.

This is now becoming really annoying why this thing is happening repeatedly.

i have attached the configuration, show dsp-group all, show voice-call status and show voice port summary outputs.

Any help will be really appreciated.

It's customer choice to renew contracts or not, but don't expect freely contributed forums to fix Cisco bugs or serious issues.
