[SIPForum-discussion] Differences between 2 Invite

[Halit Sakca]

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
