I'll provide a quick workaround in a day or two.

Bayram,
Find attached a patch (sip-options.patch) against the latest trunk, which
modifies
only mrcp_sofiasip_server_agent.c to respond incoming SIP-OPTIONS with hard
coded
capabilities.
That modification should be simple to apply to the older released versions too.
Hope this helps and let me know in case of any questions.

Thanks Arsen, I have applied patch to version we have. Also we upgraded to
latest
trunk. I will let you know the result.

Hi Bayram,
I'm glad to see it works for you.
Finally those capabilities should not be hard coded, but must be configuration
dependent. I'll implement it in the future, in the interim, perhaps it'd be
better to
respond with hard coded capabilities.
Thanks for the feedback (sometimes users only post when they need something).
Arsen.

Hi Arsen, I have bad news. There is this GVP IVR, when we made a call our the
request
reached to UniMRCP server and so the text was synthesized. But after first
call, the
other requests never reached to server. But UniMRCP server logs were always
saying this:
nta_agent: received garbage from udp/192.168.5.178:8060/sip
After we upgraded latest trunk and applied the patch you supplied. We tested the
program and I dont know why, but that time all successive requests reached to
the
server and so all texts were synthesized.
But we still started to get the same problem. And the problem is not UniMRCP's
being
not able to respond SIP OPTIONS request. The problem is Sofia-SIP treats that
SIP
message as a garbage and never let UniMRCP to process it.
I used wireshark and copied the raw text of the sip message:
OPTIONS sip:speechsynth@172.16.5.224:8060@172.16.5.224 SIP/2.0\r\n
Via: SIP/2.0/UDP 192.168.5.178:7080;branch=z9hG4bK01add590c0bced\r\n
From:
sip:VoiceGenie@192.168.5.178:7080;tag=E8ACE618-6ABC-4E89-28B7-E70EBE7E3B52\r\n
To: sip:speechsynth@172.16.5.224:8060@172.16.5.224\r\n
Max-Forwards: 70\r\n
CSeq: 1 OPTIONS\r\n
Call-ID: C4C8F662-2B45-4445-4688-8098B2559A01-7080@192.168.5.178\r\n
Contact: <sip:VoiceGenie@192.168.5.178:7080>\r\n
Content-Length: 0\r\n
Supported: timer\r\n
\r\n
When this message is sent, Sofia-SIP treats it as a garbage...and we see
nta_agent: received garbage from udp/192.168.5.178:8060/sip
message in UniMRCP logs.
It seems the SIP message is true, and I don't have any idea why Sofia-SIP
thinks that
it is a garbage. Have you ever had this problem? Any idea?
In nta.c file of Sofia-SIP, there is this function:
agent_recv_message
and there, we see this code segment:
if (sip && sip->sip_request) {
agent_recv_request(agent, msg, sip, tport);
}
else if (sip && sip->sip_status) {
agent_recv_response(agent, msg, sip, tport_via, tport);
}
else {
agent_recv_garbage(agent, msg, tport);
}
I added a code that prints out if the followings are null or not:
sip, sip->request, sip->status
And the result is:
NOT NULL, NULL, NULL
so, the message is garbage (!)
Anyway, I will be working on it, if I find anything I will let you know.
Best wishes,
Bayram

Hi Bayram,
First of all I'd suggest to setup GVP IVR and UniMRCP server on the same net,
if it's
possible. I'm not sure, but different subnets may cause this problem
(172.16.5.224,
192.168.5.178).
I need Wireshark trace and UniMRCP server console output containing both
successful
and non-successful cases. Also turn Sofia-SIP debug output on.
Before running UniMRCP server from command line set the following environment
vars
>Windows
set SOFIA_DEBUG=9
set NUA_DEBUG=9
set SOA_DEBUG=9
set NEA_DEBUG=9
set IPTSEC_DEBUG=9
set NTA_DEBUG=9
set TPORT_DEBUG=9
set TPORT_LOG=9
set TPORT_DUMP=/tmp/tport_sip.log
set SU_DEBUG=9
unimrcpserver
>Linux
export SOFIA_DEBUG=9
export NUA_DEBUG=9
export SOA_DEBUG=9
export NEA_DEBUG=9
export IPTSEC_DEBUG=9
export NTA_DEBUG=9
export TPORT_DEBUG=9
export TPORT_LOG=9
export SU_DEBUG=9
./unimrcpserver

Hello Arsen,
I am sorry for being late. But I have the logs now.
We used Cisco Systems VPN client to connect the network in which the GVP is
installed. When I find opportunity to try in the same network I will again save
the
logs and will inform you about that.
So in attachments I am sending wireshark logs, unimrcpserver console logs, and
tport_sip.log file.
In this scenario, I restarted GVP, and first two attempts were successfull
although I
have seen the same garbage messages. But later, I tried 3 more times but they
are not
successfull.
Best wishes,
Bayram

Hello Bayram,
I've just looked through the attachments.
First of all, I believe GVP uses SIP Options as keep alive message, but not to
actually learn the capabilities of server as it is described in spec.
Next, I agree with Sofia, SIP Options GVP sends is invalid. Pay attention to
SIP URI
in message start-line.
instead of
OPTIONS sip:speechsynth@172.16.5.224:8060@172.16.5.224 SIP/2.0
should be
OPTIONS sip:speechsynth@172.16.5.224:8060 SIP/2.0
The same is for SIP To header.
More over, I see only two MRCP sessions (SIP Invites), thus I have no clue why
the
final 3 attempts was unsuccessful, at least no SIP Invite reached MRCP server.
Most
probably the problem is in client side.
HTH,
Arsen.

Wow, you are right! The message is wrong! :-)
And I really appreciate your help Arsen. If you had not helped us, it would have
taken a lot of time of us.

Hello Arsen, I want to ask you another question... Does UniMRCP handles v1
equivalent
of SIP OPTIONS message, which is DESCRIBE?
Best wishes,
Bayram
ps... I get this message with Avaya IR

Hi Bayram,
The resolution for RTSP Describe is just the same as for SIP Options and the
procedure will be the same. First, I'll provide a workaround to respond with
hard
coded capabilities during the days, which should help you move forward with
your interop.
Regards,
Arsen.

Hi Bayram,
I've just committed the fix (r883) to respond to incoming RTSP DESCRIBE, see
below
http://code.google.com/p/unimrcp/source/detail?r=883
I have no enough time and an actual MRCPv1 client, which sends RTSP DESCRIBE to
test
against, nevertheless it should work, please try and let me know, if it helps.
Regards,
Arsen.

Hi Arsen,
Thanks for your effort. I will try it and let you know the result. By the way,
there
is an RTSP client program which can send DESCRIBE and wait for a respond... And
it is
very easy to use... See the link below:

wrote about.

Hi Arsen, I tried, and it works with Avaya IR. (MRCPv1)
But I really coulnt make it work with GVP...(MRCPv2)

Well, can you please add a comment to Interoperability Guide

I've never tested it myself. I'll try to dig into, if I have GVP installed on
my side...

Just an update to clarify current status of this issue.
Both client and server side resource discovery routines have already been
implemented. However, server side responses are hard coded yet. They should be
constructed based on actual configuration. I'll implement the remaining stuff,
when
find some time for it.

Hi,
I am facing a similar issue with Asterisk and Nuance. Nuance Speech Server
MRCPv2 accepts L16/97/8000 and Unimrcp was sending L16/96/8000 by default. I
changed
it to L16/97/8000. But in either case, it gives the same error at Nuance - code
error (128) unknown codec and sampling packet size (160). MRCP and SIP message
flow
seems to be okay.

Vocalizer TTS and Nuance Speech Server.

Hi Bayram,
As far the actual submitted issue has been fixed for a while, I'm going to
change the
status of this issue to fixed too.
In the meantime, as far as the capabilities of the server are still hard coded,
I've
logged another related issue-61 and will implement it when possible.
If there is anything I have missed, please let me know.
