Compare messages of SIP and PJSIP

Asterisk Asterisk SIP
1

Hi,
I am having the following problem:
Provider (client) send OPTION to Asterisk1.8 and Asterisk16 with the same format:
And response of Asterisk1.8 is different from response of Asterisk16. My provider tell to me that. The format of response of Asterisk1.8 is OK, and of Asterisk16 is not OK.
Any body can help me compare and declare response on PSIP is the same SIP.
(I see the different. With response of Asterisk16 do not have port in uri)

This is response of Asterisk1.8:

send_rpid=yes

rtp_symmetric=no

Both replies are OK, as OPTION request should be treated as normal INVITE

11.2 Processing of OPTIONS Request The response to an OPTIONS is constructed using the standard rules for a SIP response as discussed in Section 8.2.6. The response code chosen MUST be the same that would have been chosen had the request been an INVITE. That is, a 200 (OK) would be returned if the UAS is ready to accept a call, a 486 (Busy Here) would be returned if the UAS is busy, etc. This allows an OPTIONS request to be used to determine the basic state of a UAS, which can be an indication of whether the UAS will accept an INVITE request.

So what it is exactly the issue ?

Thanks Mr ambiarixg12,

I am using asterisk16.
With the same OPTION from my Provider send to my Asterisk16.
If i endable SIP then asterisk return:

My Provider accept response of SIP format. They tell to me that, when i response with PJSIP format then their system warning LinkSip to down (in their system) and LinkSip Up with SIP format response.
I dont know. If i want to use PJSIP then what i must to do?

Thanks,

4

What header in your reply is causing this ?

5

Dear Mr,
my provider do not tell to me that, why their system accept SIP response and do not accept PJSIP response. I think it are the same.

I like PJSIP but in this case i must using SIP

6

They should tell you what header active the warning, and from there we should see if there is a setting that can modify the information on this

7

Thanks for answer my question,
Operating staff in my provider don’t know. They only config on system.
My asterisk is working ok in inbound flowing via SIP(chan_sip). I am woriking for outbound via SIP.

Thanks Mr agian.

8

Do you actually need to test the connection with OPTIONS?

9

Hi Mr @david551 ,
I skipped check connection with OPTION and make a outbound with chan_sip(originate SIP/76689999@trunk_GMSC22). But the result is not good. I do not know in my provider mistake or my system mistake

This is config of peer

You need to address this error with 10.226.2.2 first

11

Thanks Mr,

That is error from my provider’s side and they are checking in their system.
I have say to them that when i send invite(outbond) to their system then i need to response 100 trying &180 ring &200 ok. It is the same
image

I am waiting respose from my provider with err

12

Just wait, because there is nothing you can’t do on your end to deal with a SIP 500 error returned by your provider

13

Thanks for reply,

I am waiting from my provider side to fix that err.

14

Hi Mr,

My provider just send to me a log SIP, that they have received from other outbound(this outboun is working )

Can you help me detail about 11000 rport in the INVITE, that my provider have received.?
I thiks that port must 5060

Thanks.

15

That rport doesn’t need to be strictly 5060 unless your provider request it as mandatory, I assume that 10.226.41.11 is your Asterisk server IP, so if that is the case change the listening port for that particular channel driver if is pjsip or chan_sip

The purpose of a rport is

“rport”,

16

Thanks for your information,

I just test with my provider. I send an INVITE with:

The IP have change: 10.226.39.49:5060 → 10.226.27.44:65476 (So their sysmte return to my asterisk 500 err)
They don’t know, and I am too.

Do you have any suggestions about this error?

Thanks.

17

I’m confused. I thought Asterisk always set rport. (force-rport is about pretending it was set in the inbound request, not about what is sent over the wire.)

Have you got application level gateway enabled on your router. That is a well known way of breaking things. What is 10.226.27.44?

I, eventually had to read this as “But my provider sent”.

18

Dear Mr,

10.226.27.44 is a node of firewall device.
my asterisk-UAC(10.226.39.49) —>Firewall (node: 10.226.27.44) → UAS(10.226.2.2)
That mean, my asterisk is located in the firewall, it has to go through the firewall device to get to uas

You are right, that is errcode, that my provider return to my asterisk when send INVITE.
