Does your SRST version supports the 8945???

What protocol are you using??

Does it have the correct SRST reference?

at other location it supports SRST mode....r u talking abt the OS version of the router?

[Chris Deren]

Post your SRST configuration and "sh ver", and let us know if the 8945 is using SCCP or SIP.

Has this work ever I mean did ever 8945 phones falls into SRST and registered ? I have had this issue in my expeirence and which could be related compatability of 8945 with IOS version and have them registered additional configuration required on the router side. . But that only can be confirmed once you send all information as asked by Chris.

Dear Carlo....thanx it worked

[Tracy Larson]

If this is a 2800 series router it is not going to work. The CME/SRST engine in those model routers does not support that model phone as Java was eluding to.

Have a look here:

if your IOS ver 15.1(4)M and SRST version is 8.6, then you have to add following IOS command in order to register phones.
