CME Hardware Conference using SIP IP Phones not working

a.burlaos
Level 1
Level 1

Hi,

 

Does anyone encountered the same issue regarding the Hardware Conferencing using SIP IP Phones for CME?

 

Scenario:

1. Phone A calling Phone B

2. Phone A pressing Conference button and calling Phone C (Phone B is put on hold).

 

Phone A tried to merge the calls but it is not working.

 

Note:

 

1. Hardware Conference bridge status for SCCP is "UP"

 

2. Debug ephone hw-conference result

You do not have ephone-dn in your config with “conference ad-hoc” added.

ephone-dn 1 octo
number A100
conference ad-hoc
no huntstop

Add as many as you want depending upon how many conferences you are looking to host.
“no huntstop” is needed to allow CME to hunt b/w dn’s i.e. inter-dn.

View solution in original post

You need it for conference. You won’t assign them to your voice register pools.

are your ad-hoc dns octo-lines.

Hello Mohammed,

 

No.

But for conference to work you need to configure

ephone-dn x octo
number A01
!
ephone-dn x octo
number A02
pre 1

Then register your conference bridge under telephony-service

Hi Mohammed,

 

I'm using SIP instead of SCCP for my IP Phones so i'm not using ephone-dn.

 

 

Regards,

 

Arvie

Hi Mohammed,

 

Does it mean that Hardware Conference will only work for SCCP and not for SIP IP Phones?

 

 

Regards,

 

Arvie

It will work for both but it has to be configured under telephony

Hi Mohammed,

 

The hardware conference was already added to both voice register global and telephony service but it is still the same.

You do not have ephone-dn in your config with “conference ad-hoc” added.

ephone-dn 1 octo
number A100
conference ad-hoc
no huntstop

Add as many as you want depending upon how many conferences you are looking to host.
“no huntstop” is needed to allow CME to hunt b/w dn’s i.e. inter-dn.

And yes you need these configured irrespective of the fact whether you have sip or sccp phones.

Hi Nipun Singh Raghav,

 

Do you mean that I need to create ephone-dn for my SIP IP Phone even though i'm using voice register pool for my SIP IP Phones?

 

 

Regards,

 

Arvie

You need it for conference. You won’t assign them to your voice register pools.

Hi Nipun Singh Raghav,

 

I’ve already tested it with 5 participants and so far it is working. I’ll try to create up to 10 participants and see if it will work also. Thank you for the information.
