Hi. Just trying to get codec working

I have a P3 Katmai processor

processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 7
model name : Pentium III (Katmai)
stepping : 2
cpu MHz : 501.164
cache size : 512 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca
cmov pat pse36 mmx fxsr sse up
bogomips : 1003.12
clflush size : 32

so I believe that the correct codecs are:
codec_g723-ast14-gcc4-glibc-pentium3.so
codec_g729-ast14-gcc4-glibc-pentium3.so

Using Sip Phone straight to Voip Proider works for G729 but not
through Asterisk

show translation gives me:

And Sip debug gives me this when I try to call with G729 Codec

You need to enable g729 in sip.conf.

Actually after you mentioned sip.conf, I took another look at it and noticed that I have it enabled for my voip context but not for my sipphone context.
After enabling in sipphone context, is now working but very broken up.
This, I don't know why or even where to start.
