[Asterisk-Users] IAX Connection - Voicepulse

[Daniel Bichara]

Hi,

I am call Japan via Voicepulse. My IAX Connection to Voicepulse was 
sucessfull. But when I put a call (dial), I get an error message:

Feb 19 22:12:23 WARNING[81926]: chan_iax2.c:1128 attempt_transmit: Max 
retries exceeded to host 66.234.228.132 on IAX2[voicepulse]/4 (type = 6, 
subclass = 1, ts=1, seqno=0)

My extension.conf:

exten => s,1,Dial(IAX2/[user]@voicepulse/${EXTEN}@VPWS)

What could be?

Daniel
