[OpenSIPStack] opensbc problems

Hi!

I'm using opensbc with IMS systems and other sip pbx. It works fine, but I have some problems now:

1. Missing 200 OK:

We tried to call an Avaya SES system through OpenSBC, but we have some trouble during the call:
the message flow is the following:
SBC sends INVITE to AVAYA
AVAYA respond TRYING
AVAYA respond RINGING
AVAYA send 200 OK
SBC respond ACK to AVAYA
AVAYA send the INVITE again
SBC respond TRYING
now AVAYA is waiting a 200 OK from SBC, but it doesnt't send.

The connection is estabilished, but it hangs up after 30 sec.

I tried it with our IMS directly and it sends the 200 OK after the TRYING.
Is it a bug or a configuration problem?

I uploaded a capture between sbc and avaya (sbc-avaya.cap), a capture between Huawei and avaya (huawei-avaya.cap) and the opensbc log.

url: http://home.mik.bme.hu/~madarassy/opensbc-bugreport2.zip

2. Removed route header

Opensbc removes Route header from the INVITE message, but IMS need it.

3. Adding and rewriting headers to a SIP message

I need to add some extra headers (e.g. Supported header) and modify some (e.g. User-Agent) in SIP messages. Are you planning to add a feature like this? Or can you help me hard-coding to the source some header modifications?

Are you planning ipv6 support?

Re: [OpenSIPStack] opensbc problems

Hi,

OpenSBC indeed failed to process the INVITE because SDP is missing. I
have commited a possible fix for this in CVS. Can you test if INVITE is
now getting propagated ?
