Hello everybody,
?
Can anyone please help me to find out exactly from which file?the SIP packets are created in the PJSIP.I'm in urgent need to encrypt the packets before transmission over internet.Actually my idea is to encrypt the SIP packets & encapsulate in the HTTP packet & then transmission over internet to connect to the Asterisk server.If anyone have any idea how to do it, please share with me.
?
?
Actually I've no practical idea, where the SIP packets are created in PJSIP code.Any help will be of great value..
?
Thanks in advance,
?
Regards,
?

Hi guys



I'm having an error message when installing apsserver2.sisx on a 5800 xpress
device (5th ed model). I know I can use VAS but the app is actually
targeting s60 3rd and 5th ed models.

The error message is "application not compatible with phone" if I proceed
with installation the app still works fine. its just the error message I'm
trying to get rid of.

Does anyone have a solution or workaround?



Regards



Jerry

We support call hold with sendonly/recvonly. As usual, to find out
what the problem is, please state the PJSIP version that you're using
and send us the log.

Hi,

i am using version 1.0.

I already identified and fixed the problem.



According to RFC 4566 (5. SDP Specification, page 10), if we put the "a=sendonly" before any media line (like "m=audio"), it is at session level and it affects all media lines.



So the following:

...

a=sendonly

m=audio .....
...
m=video ...

...



Is the same as:

...

m=audio ...
a=sendonly

...

m=video ...

a=sendonly

...



I did not check recent versions, but PJSIP 1.0 is not handling correctly the "a=sendonly" before any "m=audio".

In order to fix this i changed the function "update_media_direction" of sdp_neg.c. Every time a "a=sendonly" appears before any "m=audio", i remove it and put it in all "m=audio" that does not have the "a=sendonly".

(When i say "a=sendonly" i mean any of the following values: "a=sendrecv", "a=sendonly", "a=recvonly" or "a=inactive")



My solution is not the best one, but i can provide the patch if requested.



cheers,



Rafael Maia
