[Asterisk-Users] More Sip/Grandstream issues

[Lists]

I just checkout the cvs code for asterisk......

when I use my grandstream phone (that worked on the old code that was 
about 2 months old) I do not hear anything at all...

I get this error:
Sep 27 23:20:27 WARNING[1142127920]: File chan_sip.c, Line 444
