[SIPForum-discussion] Differences between 2 Invite

[Zuñiga, Guillermo]

SIP endpoint                  Veraz switch

21:16:49   INVITE  --------------> 

 21:16:49  <-------------- 100 Trying

 21:16:59   CANCEL ------------>                 (This message cause the call to be released)

 21:16:59   <-------------  200 OK

 21:16:59   <---------- 487 Request Terminated

 

The problem is that the MGW after Veraz Switch is not sending me ringing realy I want to discard if the

SIP Signaling have something to do in the fail.

 

Thanks Doctores.

hey mate,

to investigate more efficient could you please let me be clear about the case?

"I am sending a sip call to the same mgw  coming from differences IP-Carriers,"

what is that supposed to mean? 

A: sip client from xtelecom
B: pstn or something? media gateway (I assume)

A calls B, INV goes to proxy then routed to GW and call couldnt be established. Is that what you mean?

what IP-Carriers one of them cisco gw, other one? (and differences)

difference is clients types I think right? (SDP does not explain that!)

and if let me know about the call flow you are gonna be the one :D

good luck!


Selamlar,
Halit Sakca

Mr,

 

Who could help me.

I am sending a sip call to the same mgw  coming from differences IP-Carriers,

 

The first call with file "invite ok ethereal.txt" is a good call 

And the other call with file "invite bad ethereal.txt" is a bad call.

 

In the good call I am seeing the parameter  (Media Attribute (a): sendrecv) and in the bad call is not.

This could be affecting that the call can not be completed, and the MGW in the other site is waiting any of this parameter's or other?

 

Thanks 

Regards
