MiVoice Business Console call transfer (no ring back tone).

[saliou-ab]

I am using MiVoice Business MXe III with MiVoice Business Console. When calls are transferred from console to other destinations callers hear only silence and (no ringing).

Did some one face the same issue or have a recommendation?

Thanks in advance.

Are the phones (voice VLAN) and the console (data VLAN) on different VLANs?

Is the cos set to play music on transfer? If so, do you have a music source?

Consoles and phones are operating on LAN where VLANs are as follow:

Data VLAN = 2

Voice VLAN = 3

Yes there is an embended MoH source which is playing well, but not during the transfer.

Aren't you using SIP trunk? Maybe the option "Disable Reliable Provisional Responses" is set to No and the SIP peer does not support PRACK.

No Petr, I am not using SIP Trunks at this moment. I am using one E1 for exteernal calls.

Thanks
