Please verify that you are using the correct phoneload for CME 4.0. If the incorrect phone load is used, you will see unexpected symptoms such as this.

Hello,

From the config attached, we see that Santiago is running the latest, recommended 7.x load on the 7960.

Is the problem happening on the 7960 only ?

Hello Santiago,

I have looked at the config before and it seems ok. You may need to run some debug on sccp protocol and the voice port, to see if you can capture any discrepancy.
