Aastra Dect Integration with CUCM - Registration issue

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

Aastra Dect Integration with CUCM - Registration issue

Without having a look at the traces have you configured the SIP phones completly in other word assigned ext to Line 1 and gave it a PT and CSS?

Have you assigend that SIP phone to an end user under user management on the CUCM?

Aastra Dect Integration with CUCM - Registration issue

Hi Stefano.

In the trace you posted, I saw that Astra Devices are trying to register with unconfigured DN

"Registering line (61363) not configured"

and in the sip trace you can see a "Not Found" sent by CUCM.

Can you please check the correct configuration of SIP third party phone, digest users (one per device) and Directory Number config?

Let me know

Regards

Carlo

Aastra Dect Integration with CUCM - Registration issue

Hi Carlo,

I know the best practice in order to configure a SIP client on CUCM infact I configured on CUCM:

1) 3 local end user

     Username: 61351

     Password, PIN, Digest Credential = 61351

     Username: 61363

     Password, PIN, Digest Credential = 61363

     Username: 61410

     Password, PIN, Digest Credential = 61410

2) 3 basic SIP phone with

     DeviceName: 000000061351

     Digest User: 61351

     Directory Number: 61351

     DeviceName: 000000061363

     Digest User: 61363

     Directory Number: 61363

     DeviceName: 000000061410

     Digest User: 61410

     Directory Number: 61410

and on Aastra master base station 3 phone with end user authetication:

     Username: 61351

     Password: 61351

     Line: 61351

     Username: 61363

     Password: 61363

     Line: 61363

     Username: 61410

     Password: 61410

     Line: 61410

The strange issue is that just one registration request, the first one, is accepted by CUCM and the others it replied with Non Found; if I reset all the phones from CUCM web page or reboot the master base station the first SIP registration request change and a different phone is registred on CUCM.

It seems that CUCM accept just one requesta at a time from Astra Base Station.

I also try the same configuration of Aastra Master Base station on a CME and I'm able to see all 3 phones registered.

Is the Aastra side configured correctly?

Please see document with examples. Don't know if this is what your setup or not.

Re: Aastra Dect Integration with CUCM - Registration issue

Stefano,

The issue here is that the CUCM needs a unique source IP or source port for each SIP registration.  In your case, all 3 lines are trying to register with the same IP (10.12.2.201) and port (5060).  This results in only the first line registering successfully.  Is there anything you can do on the Aastra side so that each registration will have a unique source port?
