Hi all,

Thanks Greger, for pointing out the issue with the announcement port 
running on
port 5060.  I've tried to figure this out with my engineers, but we can't find
the config location of this announcement port thingy in the Cisco, let alone
configuring it.

As mentioned previously, the Cisco 3600 has changed it's default SIP port to
5080, but according to the ngrep report, it sends a reply (announcement) port
on 5060, therefore when SER replies back to Cisco 3600, it tries to send it
back via 5060 thus Cisco can not receive message.

We're STUCK here!!  If there're anyone out there with experience / solution in
solving this problem with the cisco, your help is needed & GREATLY
appreciated!!!

PS: I just need to get Cisco to work with SER!!  Any suggestions in an easier
method to get this working are welcome!!

Best Regards,
Samuel Yeung
