Posts: 6 		hello

i am using the sipp call simulator.

ua1:172.27.14.4
teksip:172.27.14.3
ua2:172.27.14.2
teksip forwarding the inivite message with 172.27.14.4 to 172.27.14.3 instead of 172.27.14.4 to 172.27.14.2.
attaching teksip.log

Please check in inivite message "TO" filed. attaching snapshot

As far as I see from the log TekSIP forwards incoming INVITE to 172.127.14.2 as expected. Can you also send me a Wireshark log?

Best regards,

Posts: 254 		What is the configured domain for TekSIP? Is it 172.27.14.3? If so two endpoints are registered;

ua1 : 172.27.14.4:5060
ua2 : 172.27.14.2:5060

an INVITE message is destined to ua2. That means TekSIP will forward it to 172.27.14.2:5060;

SIP req. from : 172.27.14.4:5060 (UDP) - 6/21/2010 3:22:17 PM
INVITE sip:ua2@172.27.14.3 SIP/2.0
[Via] = SIP/2.0/UDP 172.27.14.4:5060;branch=z9hG4bK-7128-1-3
[From] = ua1 <sip:ua1@172.27.14.4:5060>;tag=7128SIPpTag07b1
[To] = ua2 <sip:ua2@172.27.14.3:5060>
[Call-ID] = 1-7128@172.27.14.4
[CSeq] = 1 INVITE
[Contact] = sip:ua1@172.27.14.4:5060
[Max-Forwards] = 70
[Subject] = Performance Test
[Content-Type] = application/sdp
[Content-Length] = 131
v=0
o=user1 53655765 2353687637 IN IP4 172.27.14.4
s=-
c=IN IP4 172.27.14.4
t=0 0
m=audio 6000 RTP/AVP 0

and TekSIP forwards it to 172.27.14.2:5060 as expected;

SIP req. to : 172.27.14.2:5060 (UDP) - 6/21/2010 3:22:17 PM

s=-
c=IN IP4 172.27.14.4
t=0 0
m=audio 6000 RTP/AVP 0

same behavior can be observed in Wireshark log.

What is the problem?

Posts: 254 		No, TekSIP keeps From and To headers unchanged since they are informational headers. TekSIP alters only request URI;

SIP req. to : 172.27.14.2:5060 (UDP) - 6/21/2010 3:22:17 PM

Posts: 254 		Would you like TekSIP to route calls from 172.27.14.3 to 172.27.14.2 without registration?
