7936 cannot make conference in CM4.1(12.4-15T3)

lwai

I find out the 7936 cannot make conference calls normally in CME4.1.

The firmware used for 7936 include cmterm_7936.3-3-5-0 and cmterm_7936.3-3-12-0.If we reboot the 7936 once, it can make conference call with another parties without issue. The 7936 press the conf. softkey can make 3 parties in the conf. bridge.

After the first conf. call is hanged up, the 7936 wants to make another conference call as the first one, the user should use the arrow key to select the frist line, press resume and conference, 3 parties will be in the same conference bridge.

After the conf. call finsihed, if the 7936 wants to make conf. call ( the third times), all softkey ( transfer, hold conf.) no function.

If the 7936 was reload once, it can make conf. call again.

Show ephone register command indicate one of the lines is idle.

Does anyone have the same issue ? and how you can reslove it?

The router is 2811 platform and ios is 12.4(15)T3.

Does anyone has the same issue in using 7936 phone set in CME 4.1( IOS 12.4-15T3)??

It cannot make conference calls as another ip phone sets. All softkey are not function in the thrid times to create conf. call after reboot.

I will upgrade the IOS to 12.4(15)T4 tomorrow.

Thanks in advance!!

Hi,

Does anyone have installed 7936 in CME4.1?

Is it works fine in conf. feature?

Please update me if you have experience.

Upgrade the IOS to 12.4(15)T4 does not solve.

I am having the exact same problems with version 12.4(15)T1. I tried changing the loads on the 7936 the same as you did and have experienced the same problem. Have you found a solution?

tks

you might want to try a different phone-firmware. Check the software downloadpage for individual CME files.

Dear All,

I have tried the most update and previous firmware version for 7936, the same result.

I even try it in CME version 4.2, the same negative result.

I will open a Cisco Case.

I can only disable user to use hardware conference at this moment in order to avoid this issue happen.

Michael.

Tks Michael. I am in the same position. We are opening a Cisco TAC Case as well. I will keep you posted.

tks

I am having the same issue with the 7936 running on CallManager 6.0.

The conf key does not work.

Hi Kevin,

Can you update us the Cisco case you opened for this issue?

What is the work around provided from Cisco?

Please update us, many thanks!

Regards,

Michael.

I am also having the same issue with the 7936. Did you find out anything from the TAC?

Thanks,

Mike
