Aastra Dect Integration with CUCM - Registration issue

[Stefano Amici]

Hi community,

my customer want to integrate Aastra Dect solution to CUCM 9.1 in order to have dect phones registerd as SIP endpoint to CUCM.

I creted 3 SIP basic endpoint on my CUCM with associated end users with digest credential and configured Aastra master base station with correct CUCM ip address as a SIP registar server and end users digest credential for phones registration.

The strange issue is that on CUCM just one SIP phone is able to registered and if I reboot the master base station or reset the phones on CUCM the phone registerd changes.

From the log I found that the first registration request is accepted from CUCM, while for the others it replied with "NON FOUND" - "Line not configured".

In attach you can find SIP traces sniffed from Asstra master base station and CUCM traces downloaded from RTMT.

Thanks in advance for any support,

Stefano

Hello Stefano,

It seems that I will be facing the same problems as you.

I have CUCM 10.5 and Aastra RFP L35 with OMM 3.0.

I have downloaded the OMM3.0 documentation and I have not found any reference to the configuration of a SIP Trunk to the CUCM.

Could you provide some information how you have proceeded.

Thanks and kind regards

Christian
