CME 7.0 and Nokia E5 with SIP Client - cannot receive calls

[LBS-BZ-HI]

hi,

i have running a working system with CME 7.0 on a 2811 Router. IP Phones 7961,7921 both SCCP Clients, and a Nokia E65, E5 both SIP Clients.
The E65 are working without problems, but the E5 with VoiPSettings 3.x installed cannot receive calls - neither from E65 and SCCP Phones?

has someone any idea, where i can try to find the error? It seems that the VoipSettingsTool 3.x from Nokia is not working well...

thanks

Start checking that the phone is registering, show voice pool, debug ccsip message.

hi,

i think the register process is ok, the only difference between the E65 and E5 is following:

E5: Contact: ;expires=3600   (Here contact is a strange value)

E65: Contact: <782>;expires=3600

is that normal?

thanks

Can you collect the following debugs for a call made to the E5?

debug voip ccapi inout

debug ccsip message

Also, can you collect the following command output.

show dial-peer voice summary

hi Felipe,

Nokia E5 - Phone 781

SCCP7961 - Phone 716

thx

Konrad,

the debugs indicate that the E5 itself is rejecting the call.

Received:
SIP/2.0 404 Not Found

What extension does it show on the phone itself? Does it show 781 or something else?

[LBS-BZ-HI]

it shows me following:

Username

sip:781@10.95.180.5

Domain

sip:10.95.180.5:5060; transport= UDP

Registered

i didn't found more info.

[Felipe Garrido]

what client are you using on the Nokia phones that supports SIP registration? I have a E65 here in the lab that I can play with but it doesn't have the SIP client.

-Felipe

[LBS-BZ-HI]

i have Nokia E65 with "SIP Voip 1.0 Settings"- they are working. but the nokia E5 installed with "SIP Voip 3.x Settings" isn't working... i think the SIP client from nokia has a bug...

[Felipe Garrido]

Can you try downgrading to version 1.0 on the E5? I'll check to see if I can upgrade the E65 here in our labs.

[LBS-BZ-HI]

i cannot install the old version on the E5..

. but i found following in a forum:

-----------

When VoIP3.x registers a user, it writes a hash in the contact URI, i.e. kmjZ3YOXb_rakfnLNRhe@mydomain.org instead of 7777@mydomain.org

To invite a user, the server has to put this hash in the request-URI

-----------

sounds not good...

[jsalas]

Try this to change the directory number of the Nokia to the hash in the SIP req uri  header:

voice service voip
allow-connections sip to sip
sip     
  bind control source-interface XXX
  bind media source-interface XXX

  registrar server
  sip-profiles 1
!        
voice class sip-profiles 1
request INVITE sip-header SIP-Req-URI modify "sip:752@(.*) SIP/2.0" "sip:3HkqSha_SBZaN-Mrfjb4@\1 SIP/2.0"

!

voice register global
mode cme
source-address XXXX port 9090
no outbound-proxy
no privacy
max-dn 20
max-pool 20
authenticate realm XXXX

create profile sync 0554118347449519
!
voice register dn  1
number 752

name E52
!
voice register dn  2
number 771
name E71

To capture the hash, do a debug ccsip messages and look at the REGISTER message.

I'm in the same exact  situation, voip setting 3.x give a chance just to place and cannot receive.

i'm quite sure that is something on nokia device

In my case, i miss ringing sip response from E5

I found the solution...

every nokia present the SIP INVITE changing the telephone number with an ASCII like this : ZVW-kntKmiPbSiXyX9zP

so...

it's enough create a voice class sip-profile 1

request INVITE sip-header SIP-Req-URI modify "sip:4006@(.*) SIP/2.0" "sip:ZVW-kntKmiPbSiXyX9zP@\1 SIP/2.0"

in my case 4006 is my telephone number.... with the ascii that you have to catch from the debug ccsip messages.

Hope this help.. for me.. saved the business.

Bye
