Hi all,

-at least 2 SIP accounts

Do you know if Avaya has a IP Phone with this specifications?

IPO server edition version build 74 Vodafone SIP trunks doesn't work
Hi everyone, I encounter this issue:
The customer have extensions twinned to cell phones and trying call control but it doesn't work. They never receive a dialtone. I believe this has something to do with the DTMF protocol. They also provide some Cfg file and they were hoping to be able to transfer calls back to an extension with call control.

Any advice on this for to prove that this has something to do with the DTMF protocol but not SRTP is used on the connection between
Avaya IP Office and the Avaya SBCE.

Kindly please advice on the issue.
Thank you.
