[OpenSIPS-Users] [15066] WARNING:rr:after_strict: no socket found to match RR [1][XXX.XXX.XXX.XXX:5060]

Mon Feb 5 10:52:08 EST 2018

I think I get it now thank you Bogdan.

So I would forward the traffic using the opensips proxy, using the if (is_method(“refer”)) to the opensips box that would be the B2BUA? To bridge the call ?.

Also look forward to Opensips summit in may 😊 ill see you all there got it booked Saturday 😊

Hi Brian,

Keep in mind that you cannot make opensips act in the same time as proxy (as required by the load balancer) and as a end-point (as required by the B2BUA). Ideally is to run the two services (LB and B2B) on two opensips instances in a chain.

Sorry my apologies.

So from the beginning opensips acts as an authorization proxy which passes the call on to an asterisk box based on load (using load balancer).

I am trying to get the opensips proxy to handle call transfers and I thought the b2bua would be the best way. Initially the refer was sent to the asterisk box.

On inbound calls 

The call comes in from the carrier goes to asterisk, asterisk then passes the sip invite to the proxy which then rings the sip phone.

What I wish to achieve is a way to transfer an inbound call to an internal extension or external number.

Example: 

Caller A receives call à caller A places call on hold and dials caller B à caller B picks up à caller A presses cisco xfer and call is passed to caller B

I was hoping to achieve this using the proxy or asterisk box if possible.

I hope this helps.

I'm a bit confused. The original report was on a record_route() / loose_route() matter. But you say you have opensips as B2B, so the RR mechanism must not be used in such a case - you act either as a end-point, either as a proxy - you cannot be both for the same call.

Now you have this b2b error, during a call transfer scenario. and you mentioned LB also :)...so I'm a bit confused - could please try to put all these pieces together, so I can understand what you are doing ?

Maybe I am doing this wrong but I wanted the B2BUA module to handle the refer and bridge the calls. 

I have the B2bUA working now. However my issue is that its not able to send the replies.

incoming reply

b2b_reply (B2B.222.7591351.1517580641)

Feb  2 14:10:47 [22664] ERROR:tm:_reply_light: failed to generate 408 reply when a final 200 was sent out

Do you need anything else to help me debug this ? I am not sure why its failing to pass the reply with tm, I have enabled the param:

modparam("tm", "pass_provisional_replies", 1)

I should also note that I am using the load balancer module also. This normally deals with all call distribution. In and out.

Hi Brian,

Maybe that warning points to a routing error that prevents the REFER to be route to carrier - make a sip capture to be sure the REFER from A is properly routed and accepted by the carrier.

Hi Bogdan,

Thank you very much, so this doesn’t have any impact on why the call being transferred are dropped ?

I am trying to transfer a call using the refer method as that is what the cisco phones use.

The network is setup like so opensips proxy à asterisk gateway à carrier

Scenario:

Inbound call comes into the phone like so: carrier à ast à proxy à phone A

Phone A needs to transfer call to phone B: Phone A dials phone B à phone B picks up à phone A presses xfer button and call is dropped.

Any help would be appreciated.

Hi Brian,

That warning means OpenSIPS found a Route header (while doing loose_route) that is suppose to be of its own, but the network information from the header does not match any of the OpenSIPS SIP listeners.

When I try looking on the mailing list there are no other similar posts, could you please shed some light on what maybe causing this please.
