One Way Speech Problem With Asterix

[rumelihavasi]

Hi All,

I have 2 nortel csk1E and 1 Asterix Softswitch.

Nortels are connected SIP trunk and both working fine.

Please find details below and can you help me about the problem.

SITE A : CSK1E RLS. 5.5
SITE B : CSK1E RLS. 5.5
SITE C : ASTERIX

Site A to Site B SIP trunk
Site A to Site C E1 PRI trunk

Site A & B call themselves without problem.
Site A & C call themselves without problem.
Site C calls Site B through Site A without problem.

When Site B calls to Site C through Site A call is established, but one way speech problem.

I have tried both G729 & G711 codec same problem..


Please help me?
