Make sure your using qualify=500 in the sip.conf along with nat=yes, make sure any firewalls allow 5060 udp and tcp and random ports above 10000 in form your PBX.
If you have all that it should work.

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.

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
