Possible incorrect Speex WB handling in SDP offer #1005

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 

What steps will reproduce the problem?
1. Install jitsi client
2. make a call to a sipdriod

What is the expected output? What do you see instead?
call should establish. Instead I receive incompatible codecs error

What version of the product are you using? On what device/operating system?
2.4 on cyanogenmod 7.1, ZTE Blade

Which SIP server are you using? What happens with PBXes?
CommuniGate Pro which is most likely irrelevant because it is acting as a SIP 
proxy not changing codecs in SDP. I don't have account with pbxes, but if it 
allows direct SIP-to-SIP calls, the problem should be reproduceable there as 
well.

Which type of network are you using?
wifi

Please provide any additional information below.

Most likely this is because sipdriod only supports speex NB and gets confused 
when speex WB is offered. Disabling speex altogether solves the problem.

Already here you can see format announcement (98) without the corresponding 
rtpmap attribute which is afair not allowed for dynamic payload types.

I get the same error making calls from pjsua r2914 (Sept 2009) to SipDroid 2.7 
beta (May 2012) on sgs2 touchwiz ics. pjsua by default offers speex WB as the 
preferred codec; if I disable speex WB (leaving speex NB as the prefered) then 
it works.
