Hi, How do I eliminate Content-Length:0 from sip reply when using sl_send_reply? I wanted to generate 200 ok, with SDP payload. I appended headers like below. The packet seems ok except there is extra "Content-Length:0", which is causing problems. Any workarounds?
The packet being generated is: Note the extra content-length: 0 at the end.

Hello,
What leads you to the conclusion that the
Content-Length: 0

Hi Alex, I am adding my own SDP body to the reply and set the content-length to 350 already. The extra content-length: 0 is causing it to be malformed.
Question: Is there a way to generate SIP reply with SDP payload from config file. I saw there is uac_send_req but no support for reply so far...Please suggest.

Why are you generating your own SDP body? What are you trying to accomplish?
Every once in a while there is a legitimate reason, but 99% of the time that is the wrong approach to whatever problem you're trying to solve.

I want to place the customer call on hold while I look for the "agent" to answer the chat call. Daniel confirms that for a brief moment I can hold the calls on Kamailio. Eventually we are looking for "FreeSwitch" to help us. Hence this is what I am trying:
1) When customer invite comes - let it terminate on Kamailio for a while - If msrp message comes from customer, reply "pls hold for agent to be available" from Kamailio 2) When the agent becomes available, send "Refer" to customer to connect back again. - Now customer and agent can talk directly to each other.
So, for the step 1, I am generating SDP from Kamailio so Customer has everything setup properly. How do I do that from config?
If this is not right way to place a MSRP chat call on hold, what is the right way. Please suggest.
Thanks Pranathi

Hello,
What leads you to the conclusion that the
Content-Length: 0
header is "extra", and in need of a "workaround"?

It's a legitimate aspiration, just not one that Kamailio is designed to service, since it's a proxy - it just passes messages. For instance, one cannot "terminate" an invite to Kamailio "for a while". As a messenger, it has no means of doing that. You need an actual user agent involved.

Actually the scenario might work with some bits of coding, in the idea that the INVITE is answered for the purpose of keeping it on hold, so no real communication happens. Moreover, if I got all the details properly, here is about MSRP (text messaging), not audio/video session.
Cheers, Daniel

Hi Daniel, Just wanted to confirm my understanding here. Are you hinting towards INVITE (hold) message illustrated here (http://www.tech-invite.com/fo-sip/tinv-fo-sip-service-01.html) Here is how it lays out: 1. Customer sends INVITE requiring MSRP chat 2. Kamailio will accept the invite and complete the session setup - send 100 Trying, 180 Ringing and 200 ok. 3. Kamailio will send INVITE(hold) to customer 4. When the agent becomes available, Kamailio will send "refer" to connect to right agent directly.
Please share your comments on this.
Thanks Pranathi.

Hello,
you don't need to set the Content-Length yourself, kamailio does it automatically when the body of a message is changed.

Hi Alex, I am adding my own SDP body to the reply and set the content-length to 350 already. The extra content-length: 0 is causing it to be malformed.
