Trancoding Question

[lnofal]

Hello

I am developing to a card prepaid proyect, with Cisco 3660 Ios 12.3(4), IVR/TCL 2.0, Openradius and SqlServer. System IVR must take care of the calls on IP leg (incoming), and POTS leg is outgoing.

Caller-->PSTN1-->VOIP GW(non-cisco)-->WAN-->Cisco 3660(IVR) -->PSTN2-->called

- The PSTN2 works with G711alaw codec (Latin america).

- The prompts are encoded with G711 ulaw.

- The comunication between VOIP Gateway (non-cisco) and Cisco 3660 I want to make using codec g711 ulaw (or in the best one of the cases G729)

I need to know if this scheme is supported by router Cisco 3660, or must to use another software, as CallManager, so that realize tasks of transcoding?

thanks .

Leonardo

New, smaller scale, standalone DSP services modules will be made available shortly after Cisco CallManager 3.1 releases to more affordably provide transcoder and conference bridge services at small- to medium-sized remote sites.

the below document gives a list of Transcoding devices.
