You can transmit a recorded audio in the form of a WAV file over a SIP signal if you convert it to the appropriate codec first. This does not require a sound card to transmit this audio. A sound card is only required to listen to the audio. Which codec to use depends on the platform. Here is a link for converting to appropriate codecs when using Asterisk. There are a lot more if you just Google something like “audio codec conversion”.
A simpler approach is to just use a platform that does this for you, like Voxeo Prophecy. This is a software only IVR solution that has a 2 port version for free. It is easy to install and program using the open standard VoiceXML. It will play back audio files recorded in a WAV file format and the telephony interface is SIP.
