Re: [OpenSBC] How to eliminate MERGED REQUEST error

[Joegen B. <joe...@gm...>]

First, download the latest from CVS.   I have recently moved the transport listeners to its own section in the admin (SIP-Transports).  It would allow you to specify the interface address and port to be used by the back-door.  Whe you trombone/hairpin back the call to OpenSBC, make sure that it is routed through the backdoor (default 5062) and not through the main transport listener (default 5060).  This would allow the backdoor to change the call-id making it possible for OpenSBC to treat the call separately from the original call.

Hi all,
I have done below setup by minor modification in OSBC code.


------>| OpenSBC | ----------> | OpenSIP |

<------|                 | <---------- |                |


When calls come from outside net to OSBC, OSBC adds the IP address of source in custom SIP header variable "SRC-URI" (for that I done minor midificaiton in SBCRoutingHandler.cxx) and route the call to OpenSIP.

OpenSIP find out route based on custom SIP header variable "SRC-URI", and add the destination URI as custom SIP header variable "SBC-Force-Route", route the call back to OpenSBC.
So that OpenSBC should route the call to uri set in "SBC-Force-Route" variable. 

But when I tested with sample calls, OSBC route the call to OpenSIP that part work well, but when call comes from OpenSIP (by SBC-Force-Route set to proper URI), OSBC does not route the call, and end up with below messages:

========================================================================

I have attached whole log in pastebin, you can find it on link:

What should I do to eliminate error "Merged Request..."? 

Thanks,
