Codecs g729 simultaneous call

I have a problem using the codec g729 and simultaneous call. I used a 256 kbit/s internet line and a PAP2 of Linksys. When I used the two ports simultaneous to perfom a call, one of the port break after 22 seconds of call while the other port is continuing the call. How can I fix that pls?

Thank´s in advance


How does it break? Please provide appropriate logging output.

most probably is a hardware limitation in PAP2 -> please find some user comments here:
