SIP Softphone for Windows Mobile 6 - works on PocketPC

Hi, I did testing getting good results .
This SIP client works fine on my HTC Touch ELF with wifi connection, also is registered ok on sipserver Asterisk (it behind nat and another network), the speakerphone is recognized too.

To considerate:

+ SIP server: Asterisk server v.1.6 standar ( codec g729 opensource).
+ Audio quality: g711u codec is the best, gsm codecs works but not fine, g729 g723 and g711a doesn't work.
+ Recording: work fine.
+ DTMF: dtmf rfc2833 recognition.
+Video: not supported
