When I put the asterisk server inside NAT, I do not get any SIP-retransmission problem, SIP-trunk seems to work on all calls.

Why asterisk is occasionally unable to get SIP packets out to SIP gateway when connected to PUBLIC IP?

Did some body had this problem before?

Hi,

We are using VOIP-SIP gateway to route outbound PSTN calls.

Recently, I am getting   == No one is available to answer at this time

message, after making 5 SIP attempts (Retransmitting #5 (no NAT):),

and the calls are going out through alternate Zap-trunk.

I do not see any hit (sip-debug traffic) on the voip-gateway for the failed calls.

Strange thing is that this is happening randomly, half the call I make are able to get through the SIP-Trunk.

I will really appreciate any input/suggession on this.

Obaid.

Here are my conf files, followed by SIP debug output on asterisk.
