[Asterisk-Users] client reinvitation problem

[vk at akcecc.net]

Hello All!

There is description of my problem with Asteriks below.
Asteriks CLI says: 
"File chan_sip.c, Line 415 (retrans_pkt): Maximum retries exceeded on call"

Sip debug on the server gives the next:

Retransmitting #5 (no NAT):
SIP/2.0 200 OK
Via: SIP/2.0/UDP 192.168.0.26:5060
From: <sip:8523 at 192.168.0.24;user=phone>;tag=106403508
To: <sip:500 at 192.168.0.24;user=phone>;tag=as0771c6f9
Call-ID: 3296035458 at 192.168.0.26
CSeq: 1 INVITE
User-Agent: Asterisk PBX
Contact: <sip:500 at 192.168.0.22>
Content-Type: application/sdp
Content-Length: 209

8523 is Cisco ATA-186 

The sip.conf content:
 - - - - - 
[cisco8523]
type=friend
username=8523
secret=test
nat=no                
host=dynamic
canreinvite=no
qualify=300
defaultip=192.168.0.26                 
 - - - - - 

Why I place a call to Asteriks. I hear some invitation but connection brokes
when retransmit exceed.

Could anyone give some advice or solution.
Thanks in advance
