You do have :
nat_enable: "1"
nat_received_processing: "1"

On the Ciscos?

I am having a similar problem... I get the same message, but inbound
calls can go through.... This is only Cisco phones that are behind NAT.
I have tried your recommendations from below, but still no luck.. User
can make outbound calls, just can't receive any.  Any ideas would be
greatly appreciated.. I even tried to change the timeout value in
chan_sip, but it just waits longer to fail.. Just dosen't seem to want
to communicate...

Thanks,

Are you using Cisco phones. ?


I had this issue with my cisco phones. I didn't had any issues with
dropped calls. All I did to fix this was set a prefered_codex and set
proxy_register to 0.


I hope this helps.

retrans_pkt: Maximum retries exceeded on call [EMAIL PROTECTED] for seqno 102 (Request)


This has been brought up in the previous post but it does not seem to
have an answer for it so far.

I cvs the stable v1.0 this morning after compiling and
installing I have calls drop 1 minutes into the connection with the above message.


If anyone has any idea of this occurrence.

I have set up sip.conf:

canreinvite=no
