[Asterisk-video] 3G <-->SIP audio problems

[aster vdo]

Hi,

I am doing a video call from a 3G to SIP.

The video works fine, but there is no audio for both the parties.

I using Asterisk 1.4.20.1

and i get the following warning message on asterisk

WARNING[15840] chan_sip.c: Asked to transmit frame type 8192, while native
formats is 0x4 (ulaw)(4) read/write = 0x0 (nothing)(0)/0x0 (nothing)(0)

and the show channel  commands results in the following output.
