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

[Alan Su]

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
