CUCME SIP extensions not registering

[karpathian]

Hello to all,

I have a Cisco 2811 router, running IOS version 15.1(4)M and Call Manager Express 8.6. I have also setup the router to serve out SIP to a few Cisco 9971 SIP phones. I have been able to work out exactly the config required for these phones to work as far as audio and video calls are required but I have a final problem.

Under the "voice register global", when I run the command "create profile" in order to create the .cnf.xml files, I find that one piece of information is always missing, which in consequence makes these phones to not become registered against this SIP server.

It is the field called: "name" which should contain the actual phone number extension for that particular SIP phone.

How can this field be automatically-populated?

partial example .cnf.xml

<sipLines>

<line button="1" lineIndex="1">

<featureID>9</featureID>

<featureLabel></featureLabel>

<proxy>USECALLMANAGER</proxy>

<port>5060</port>

<name></name>    <<<<<------------- MISSING Line number extension !!!!

Hi,

Do you have the following line already configured?

voice service voip

  sip

     registrar server

Hope it helps, please rate if it does.

Hello Adrian,

Unfortunately that didn't do the trick. Here is the additional relevant sections:

voice service voip

media flow-around

media transcoder sync-streams

allow-connections h323 to h323

allow-connections h323 to sip

allow-connections sip to h323

allow-connections sip to sip

signaling forward none

h323

  no call service stop

  call start slow

sip

  bind control source-interface Vlan1

  bind media source-interface Vlan1

  registrar server

  asymmetric payload full

  video screening

!

Anything else I should be looking at? When I run the "create profile" command, I get files of the type: SEPxxxx.cnf.xml for these 9971 phones, but that's what these phones request for anyway when using the "load 9971 sip9971.9-1-2" command.

As I mentioned above, I have a working file but every time I reload the router or when I type the command "create profile", I keep losing that one setting. Everything else is fine!

I figured it out!

I noticed that my 1st SIP extension would always get the right settings and become registered so after some further investigations, I found that in the section "voice register pool  xx", I had been defining line 1 incorrectly.

For example

Instead of: number 1 dn 3 (match line 1 to the "voice register dn 3" profile)

I had: number 3 dn 3

Thus my line 1 was never defined properly and hence the xml tag in the SEPxxxx.cnf.xml file was never populated.
