Thank-you all for the tips.... I was out of town for a meeting, that's why I couldn't reply any sooner. I will give it a shot and let you all know how it goes. Paul, as for the corrupt c= field, what can I do or go around it?!? Again, my setup is based on the ONSIP.org document which calls use_media_session(). If this is the case, what can I do or what should I pay attention to??
Thank-you all for your input.... If this works, I think I'm gonna start up a HOW-TO document for Cisco 3600 and SER, and hope that all your contributions would be helpful for both me and everyone else dealing with Cisco 3600 and SER.
Cheers!

Smy,
One thing to keep in mind when dealing with Cisco 3600 routers (and others with ALG functionality) is that if you are using mediaproxy or rtpproxy and accidentially call use_media_session() or force_rtp_session() more than once when dealing with NATed clients, that SER will corrupt the c= field in the SDP payload and the Cisco 3600 will refuse to pass that message -- we can call this a "feature" :-)

Looks like the cisco box never receives the trying... U SER-ip:5080 -> cisco-ip:5060
If Cisco listens to port 5080 and not 5060, it's obvious... However, the box announces 5060 in: Via: SIP/2.0/UDP cisco-ip:5060
So, you need to change the cisco's announced port. Should be some parameter somewhere... g-)

Hi all,
I'm currently working with a cisco3600 with SER 0.9.2. Thanks to Onsp.org http://Onsp.org, I can land calls from SER to Cisco 3600
without any
problems. Yet I'm experiencing some problems with Cisco3600 passing calls onto SER.
My setup is as follow:
Cisco 3600 ==> SER+Mediaproxy ===> IP Phone
When a call come in via DID method through the Cisco3600, SER received the all SIP messages (I got it via ngrep), yet the call couldn't pass onto the IP Phone.
Currently, all devices (including cisco) have been configured to use port 5080 instead of port 5060 due to port restrictions on the network, and that I have specified the ip in the trusted table under mysql. Yet I don't know why the call still can not get through. The following are the logs I received from ngrep and cisco..... Any help is welcome and is GREATLY APPRCIATED!!
