I have a problem of some codec mis-match issue while making calls with freeswitch, the calls coming are all with only one codec G711 and I am amazed with the strange behaviour of Free-Switch

that some times it responds the calls with the same codec and making them successful but numerous times it responds with G729 & hence calls got failed due to this. I have disabled the G729 codec in 

all my configuration but I don't know where is it coming from.

Any help regarding it would be highly appreicated.

Thanks
