Fwd: [Serusers] SER+NAT+RTP PROXY

[Karunakar Chemudugunta]

Hi List,

  Thanks for response for my previous mail.

I am unable to establish voice connection between two user agents
which are located one in public network and other is in provite
network. I am using SER+NAT+rtpproxy as proxy servers. I have serched
seruser mailing list for solution and I didn't find any. Please help
me in below senerio.

Elements
-----------------
1)   UA 'X'           ( in public internet with IP 209.233.XXX.XXX)

2)   SIP SER with NAT helper(CVS version)  + rtp proxy  on same
machine(http://www.portaone.com/~sobomax/rtpproxy.tar ) with one
external  public IP and internal privite IP)

3)  UA 'Y' - in side private domain with 172.16.12.XXX)  ip address.

_______________                        __________________      ________________
| Public               |                       |  Ser +NAT+rtpproxy |
   |  UA 'Y'                 |
|UA 'X'                 |--->Firewall ---> | 172.16.XXX.XXX
|---->|  172.16.XXX.XXX   |
|209.233.XXX.XXX |                       |       Internl IP
|     |                            |
|______________|                        |__________________|
|_______________ |
                                         Public IP 203.209.XXX.XXX

I am trying to accomplish to make call from UA 'X' to UA 'Y'. i'e
calls from public IP to private IP using SER as my signalling proxy
and rtpproxy as proxy for RTP.

FYI - I am using estara softphone as X and Pintel Softphone as Y.

SER is succussfully etablishing connection between two use agents and
but it is failed to forward rtp between two UAs. No voice.

Please find attached ser.cfg file.

I assume, may be because of below errors.

Again thanks for help.

Regards,
KRC
