[cisco-voip] SIP Trunk between CallManager 6 & OnDO Server

[Ryan Ratliff]

Jason was correct in that it's on the SIP security profile and not on the
SIP profile.

System->Security Profile->Sip Trunk Security Profile

Hi Ryan, Jason:

 

Thanks so much for your reply.

I check the Standard SIP Profile & SIP trunk configuration, but I can't find
the setting of changing transport from TCP to UDP. Could you advise how to
do that? My CCM version is "6.0.1.2000-4". Appreciate~

 

Regards,

Alan

I'm not sure what OnDO is but it's rejecting the TCP session CUCM is trying
to establish for the SIP call.  You can try changing the transport from TCP
to UDP in the SIP profile for the trunk.

Dear All,

 

I'm having a problem to make call from IP Phone registered in CCM6 to SIP
phone (X-lite) registered in OnDO.

 

Topology:

IPPhone -- CCM6 <-- SIP Trunk --> OnDO -- XLite

 

All devices are in the same network segement.

 

When I make a call from XLite to IPPhone, it works. But when I tried to make
call from IPPhone to XLite, it just returned busy tone. I use Ethereal in
OnDO server to capture packets, it did receive the packet from CCM6. The
flow as below:

 

1. (source) CCM6, (destination) OnDO, (protocol) TCP, (info) 38988 > sip
[SYN] seq=0 win=5840 len=0 mss=1460 tsv=612823 tser

2. (source) OnDO, (destination) CCM6, (protocol) TCP, (info) sip > 38988
[RST, ACK} seq=1 ack=1 win=0 len=0

 

Any suggestion would be very grateful, thanks a lot~

 

Regards,

Alan
