Problems with chopping sound in one direction

Hello again...

I have a problem with sound from Uplink to other party.

Situation look like this:

Skype caller --> Skype with Uplink --> Asterisk --> IP Phone

When I call to Skype user i have a problem with chopping sound but only in one direction.

Skype user hear clearly but IP Phone user hear chopping sound.

So I have made a test with connection like this:

SIP Soft Phone ---> Asterisk --> IP Phone

and there is no problem...

So i think something is not right with voice coming from Uplink.

Got any idea what could be wrong?

Addition to previus post

Here is my sip.conf

[skype]

type=friend

username=skype

secret=xxxx

context=from-skype

host=dynamic

canreinvite=yes

callerid="Incoming Skype"

port=5070

insecure=very

disallow = all

allow = alaw

Did you find a solution. I've got the exact same problem.

SIP softphone gets it 10-20% of the time.

DISA based calls 100% of the time.

Thanks

the problem seems to be the same like for Express Talk, you can check the similar thread in Express Talk forum
