Getting Speex Decode Error while start conversating on call using Speex Codec

```
I have build successfully the source and installed the app.
Changed configurations and setup Speex as default to use.
Sip suuccessfully registered with Asterisk and negotiated Speex-NB for session.
On making call the ringtone hears louder and clear.
On picking call on other side, the problems starts:
1) The voice is louder at my end whereas it is noticeable fader at the other.
2) Call continues to run untill end press. But some missings in voice is
noticed on hear, on both ends.
3) Noticed following Speex Decoding Exception in Logcat Logs.

***ERROR: function: "tdav_codec_speex_decode()"

```

Review the attached errorCatlogs.log and trace tdav_codec_speex_decode(), the function named in the Logcat error. Reproduce a call using the negotiated Speex-NB codec and determine whether the decode exception correlates with the missing or uneven voice; done means two-way audio is clear without that exception.
