Hi, i have a cluster of callmanagers 5.1 on a local site there are also some remote sites where are some ip phones. There is one site that has 600 ms of delay and the phone that is there is getting unregistered each certain time.

Do you know if i can do something to prevent this, the carrier told that he can not reduce the delay.

Thanks in advanced.

Hi, it is a satellital link ... actually i had configured the keepalives every 150 seconds and the phone still gets unregistered. The phone is connected to an hwic 4 fastethernet card that is on a 2811.

Any idea ...

Thanks in advanced

Hi, since you have a 2811, configure CME on it, and a trunk between it and the central site.
