[Asterisk-Users] Maximum retries exceeded

[Tim P]

What does this mean?  I have a sipura 3000 with an analog line that I
have created as a trunk.  Incoming calls make it to the sipura but not
to the pbx.  However I can make outgoing calls but have no audio.  I
thought it might be a codec issue so I set disallow=<blank> and
commented out the "allow=".  I get the following in my logfile:
build_route: Contact hop: satelliteout
Jun 2 21:06:33 VERBOSE[2393]: -- SIP/satelliteout-af86 is ringing
Jun 2 21:06:33 VERBOSE[2393]: -- SIP/satelliteout-af86 answered SIP/100-6eab
Jun 2 21:06:33 VERBOSE[2393]: -- Attempting native bridge of
SIP/100-6eab and SIP/satelliteout-af86
Jun 2 21:06:39 WARNING[2393]: Maximum retries exceeded on call
c207e46a-baa6c1e4 at 192.168.5.100 for seqno 102 (Non-critical Response)

Satelliteout is my outbound trunk and the call is being made from extension 100.
Any idea what this means, I don't see anything that indicates an error
when running asterisk -rvvvvv in the console, this is taken from the
asterisk log files.

Any help is greatly appreciated!
