[Speex-dev] Help needed regarding AGC

Hello All, 
I use AGC as one of speex preprocess options in VOIP application. In most cases it works very fine.
However, at the very beginning of a call when no one has started talking [ and some times in the middle of calls], AGC makes large noise and it gradually increases. Interestingly, when someone starts talking, from that point it works very well. 
Is it the normal behaviour? Since there is no level to compare at that point, it may assume no speech as normal talk. 

Can anyone please put some light on this issue. Thanks in advance.
