The Acme Session Director realms can be configured for Transparent DTMF (RFC 2833 to RFC 2833, or SIP Info to SIP Info), RFC 2833 to SIP Info, SIP Info to RFC 2833, or dual-mode where one realm is set to Transparent and the other realm (facing UC) sends both event types. This is common where one SIP server requires one DTMF type then redirects the call to another SIP server that uses another DTMF type.</div><div><br></div><div><br></div><br><div><div>On Jun 24, 2009, at 1:44 PM, Jason Aarons (US) wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div lang="EN-US" link="blue" vlink="purple"><div class="Section1"><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; ">I have a SIP Trunk from Verizon Business running thru ACME Packet box to CallManager 7.1(2a) which then routes to users voicemail on Unity Connection 7.1.2a connected via SIP trunk.<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; ">If I press Zero or another dtmf key press does Unity support RFC2833 for DTMF or is a dynamic MPT resource needing to be invoked ?<span style="font-size: 10pt; font-family: Arial, sans-serif; "><o:p></o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div></div><div><br class="webkit-block-placeholder"></div><hr size="1"><div><br class="webkit-block-placeholder"></div><p><strong>Disclaimer: This e-mail communication and any attachments may contain confidential and privileged information and is for use by the designated addressee(s) named above only.
