Transfer Call

My Customer have a CallManager 5.1.3 and your topology He have too PBX TDM that will be migrate to IP Telphony in the future. Today I do transfer call between directory numbers of Callmanager normally and I do transfer of PBX TDM to Telephony IP Telephony normally too. My question is: It's possible to do transfer call between CallManager and PBX TDM? If is possible, who I can do?

Re: Transfer Call

The DPNSS Service Interworking with Cisco CallManager Using QSIG Tunneling feature enables the integration of CCM into the legacy TDM PBX networks across the QSIG tunnel and will support the following features: Path Replacement, Call Completion, Message Waiting Indicator, Call Transfer, Call Diversion and Call ID Services.

In traditional TDM-based PBX telephony, call transfer and forwarding usually operate within the limited scope of a single PBX system and, therefore, are simpler operations. For example, you are often limited to call transfers between extensions on the same PBX only.

The Call transfer service supports call transfers between QSIG PBXs and the Cisco CallManager. It supports transfers between an IP phone connected to a CCM and a phone connected to a QSIG PBX.
