Summary:                    reINVITE --> Ignoring this INVITE request -->
Hanging up call - no reply to our critical packet.
Description: 
Under light load this does not occur. However, when Asterisk serves more
than a few calls my provider resends the initial INVITE. Then you see the
following in the log:
[May 22 18:46:05] VERBOSE[26472] logger.c: Ignoring this INVITE request

Then follows retries and about 20 seconds after the call is initiated it
is terminated by Asterisk:
[May 22 18:46:25] WARNING[26472] chan_sip.c: Maximum retries exceeded on
transmission N2EzNDEyOGFmNGNmZmY0NGM4NmJlMmZmZWIzMDg3Mzk. for seqno 1
(Critical Response)
[May 22 18:46:25] WARNING[26472] chan_sip.c: Hanging up call
N2EzNDEyOGFmNGNmZmY0NGM4NmJlMmZmZWIzMDg3Mzk. - no reply to our critical
packet.

Below the SIP HISTORY for the dialogue is attached. I've tried to sort
this out with no success. There seem to be some miscommunication between
Asterisk and my providers sip server. This can and have also occurred
during calls, exactly the same outcome.
