You haven’t specified what version of Asterisk you are using or what the scenario is, and you haven’t given the configuration. It’s unlikely anyone can help with this amount of information.

Hi @gaurang.gohil
Firstly, H.264 is a video codec, whereas G.711A/U (alaw, ulaw) are audio codecs.
What are you going to achieve with such kind of “transcoding”?

Secondly, Asterisk does not support video transcoding - only passthrough (look here for details)

However, in order to use a codec (and H.264 is no exception), there is no need for transcoding.
So, please provide details requested by @jcolp
