freetdm api - ftdm_channel_read()
by Juraj Fabo 29 Aug '11

29 Aug '11

Hi I'm prototyping an application which uses libfreetdm above the sangoma isdn stack and sangoma a104d card. I would like to ask for help about proper reading of voice from the particular channel. According to return value of sangoma_get_rx_queue_sz() the default rx queue size is 10. I did tests when application skipped several reads on given channel, then called ftdm_channel_read() w/ zero timeout in a loop while the return value of read was successfull - it was really 10 frames which were then possible to read. How can an application do this reading of a channel by the means of the freetdm api in more nice way? I did not find a better way yet, than to read it in the loop. Any way to explicitly read the number of available frames? Actually, why the ftdm_channel_read() does not read them ALL at once and sets the number of read bytes via *datalen output parameter? (assuming provided *data buffer is large enough) In my tests, always 160 bytes were returned in one particular read. thank you juraj

Problem with receiving a NOTIFY after sending a SUBSCRIBE request

29 Aug '11

Hello, I'm testing a SIP stack for an embedded device. The device, among other things, is capable of informing a user about pending messages on the voicemail. It does that by subscribing to the message-summary. Below some wireshark traces (172.16.30.68 is my device, 172.16.31.10 is FreeSWITCH): REGISTER sip:172.16.31.10 SIP/2.0 Via: SIP/2.0/UDP 172.16.30.68:5080 ;rport;branch=z9hG4bKPj051b000000035ea40edf Route: <sip:172.16.31.10:5060;lr> Max-Forwards: 70 From: <sip:399510002@172.16.31.10>;tag=051b000000025ea40edf To: <sip:399510002@172.16.31.10> Call-ID: 051b000000015ea40edf CSeq: 1 REGISTER Allow: INVITE, ACK, CANCEL, BYE, OPTIONS, INFO, SUBSCRIBE, NOTIFY User-Agent: My_Sip_Device Contact: <sip:399510002@172.16.30.68:5080>;transport=udp Content-Length: 0 SIP/2.0 401 Unauthorized Via: SIP/2.0/UDP 172.16.30.68:5080 ;rport=5080;branch=z9hG4bKPj051b000000035ea40edf From: <sip:399510002@172.16.31.10>;tag=051b000000025ea40edf To: <sip:399510002@172.16.31.10>;tag=mQrcXUcvrtUmS Call-ID: 051b000000015ea40edf CSeq: 1 REGISTER User-Agent: FreeSWITCH-mod_sofia/1.0.head-git-38e3f5f 2011-08-09 03-09-19 -0400 Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, UPDATE, INFO, REGISTER, REFER, NOTIFY, PUBLISH, SUBSCRIBE Supported: timer, precondition, path, replaces WWW-Authenticate: Digest realm="172.16.31.10", nonce="3139f996-c814-11e0-93d2-05aa0ee343d6", algorithm=MD5, qop="auth" Content-Length: 0 REGISTER sip:172.16.31.10 SIP/2.0 Via: SIP/2.0/UDP 172.16.30.68:5080 ;rport;branch=z9hG4bKPj051b000000065ea40edf Route: <sip:172.16.31.10:5060;lr> Max-Forwards: 70 From: <sip:399510002@172.16.31.10>;tag=051b000000045ea40edf To: <sip:399510002@172.16.31.10> Call-ID: 051b000000015ea40edf CSeq: 2 REGISTER Allow: INVITE, ACK, CANCEL, BYE, OPTIONS, INFO, SUBSCRIBE, NOTIFY User-Agent: My_Sip_Device Contact: <sip:399510002@172.16.30.68:5080>;transport=udp Authorization: Digest username="399510002", realm="172.16.31.10", nonce="3139f996-c814-11e0-93d2-05aa0ee343d6", uri="sip:172.16.31.10", response="1e95409a562c074cbe6df148a85107ef", algorithm=MD5, cnonce="051b000000055ea40edf", qop=auth, nc=00000001 Content-Length: 0 SIP/2.0 200 OK Via: SIP/2.0/UDP 172.16.30.68:5080 ;rport=5080;branch=z9hG4bKPj051b000000065ea40edf From: <sip:399510002@172.16.31.10>;tag=051b000000045ea40edf To: <sip:399510002@172.16.31.10>;tag=N0H5ypXZN3H7m Call-ID: 051b000000015ea40edf CSeq: 2 REGISTER Contact: <sip:399510002@172.16.30.68:5080>;transport=udp;expires=180 Date: Tue, 16 Aug 2011 14:29:47 GMT User-Agent: FreeSWITCH-mod_sofia/1.0.head-git-38e3f5f 2011-08-09 03-09-19 -0400 Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, UPDATE, INFO, REGISTER, REFER, NOTIFY, PUBLISH, SUBSCRIBE Supported: timer, precondition, path, replaces Content-Length: 0 SUBSCRIBE sip:172.16.31.10 SIP/2.0 Via: SIP/2.0/UDP 172.16.30.68:5080 ;rport;branch=z9hG4bKPj051b0000000a5ea40edf Max-Forwards: 69 From: "399510002" <sip:399510002@172.16.31.10>;tag=051b000000085ea40edf To: <sip:172.16.31.10> Contact: <sip:399510002@172.16.30.68:5080> Call-ID: 051b000000095ea40edf CSeq: 1 SUBSCRIBE Event: message-summary Accept: application/simple-message-summary Allow-Events: message-summary User-Agent: My_Sip_Device X-Serialnumber: LMZ091218000026 Allow: INVITE, ACK, CANCEL, BYE, OPTIONS, INFO, SUBSCRIBE, NOTIFY Route: <sip:172.16.31.10:5060;lr> Content-Length: 0 SIP/2.0 200 OK Via: SIP/2.0/UDP 172.16.30.68:5080 ;rport=5080;branch=z9hG4bKPj051b0000000a5ea40edf From: "399510002" <sip:399510002@172.16.31.10>;tag=051b000000085ea40edf To: <sip:172.16.31.10>;tag=p9ay0He3jc8Sg Call-ID: 051b000000095ea40edf CSeq: 1 SUBSCRIBE Contact: <sip:@172.16.31.10:5060> Expires: 60 User-Agent: FreeSWITCH-mod_sofia/1.0.head-git-38e3f5f 2011-08-09 03-09-19 -0400 Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, UPDATE, INFO, REGISTER, REFER, NOTIFY, PUBLISH, SUBSCRIBE Supported: timer, precondition, path, replaces Allow-Events: talk, hold, presence, dialog, line-seize, call-info, sla, include-session-description, presence.winfo, message-summary, refer Subscription-State: active;expires=60 Content-Length: 0 After sending the 200 OK, FreeSWITCH does not send the NOTIFY. If you look at the Contact header of the answer to the SUBSCRIBE you will notice that the part before the "@" is missing. I guess this is because SUBSCRIBE request does not contain the whole URI, just the host part. That is because our customer wants it done this way; the request line should look like this: SUBSCRIBE sip:voicemail_server SIP/2.0 and the To: header should look like this: To: <sip:voicemail_server> My question is: how can I make FreeSWITCH (the NOTIFY part anyway, other things are working OK) work with such a device? Thanks. Regards, Tom

Build problem with mod_python CentOS 5.5 Python 2.7
by John O'Brien 29 Aug '11

Hi, I am trying to install mod_python on CentOS 5.5 x86_64. Have downloaded the source of Python 2.7.2 built and installed it # cd Python-2.7.2 # ./configure # make # make install All good!!! Have downloaded source of FreeSWITCH 1.0.6.

Delete voicemail greeting?
by Yehavi Bourvine 28 Aug '11

28 Aug '11

Hello, In the voicemail menu (option 5) there is a way to record a new greeting or select a pre-recorded one. However, I did not find a way to delete the greeting and return to the deault one (so I am doing this for users by deleting it from the database). Is there such an option that I am not aware of? Thanks! __Yehavi:

Parsing Error on conference_set_auto_outcall
by Duvid Rottenberg 28 Aug '11

28 Aug '11

I was using the Mad Boss example and I was getting parse errors, I traced it down to the following line, <action application="conference_set_auto_outcall" data="${group_call(sales)}"/> when group_call gets expanded it adds the default dial string for each member of the group which ends up looking something like this. [sip_invite_domain=10.195.94.25,presence_id=1001@xxx.xxx.xxx.xxx]sofia/internal/sip:1001@xxx.xxx.xxx.xxx, [sip_invite_domain=10.195.94.25]error/user_not_registered The parse error I got "Cannot create outgoing channel of type [presence_id=1003(a)10.195.94.25]error cause: [CHAN_NOT_IMPLEMENTED]" indicated that it was treating the comma inside the brackets as a separator between 2 dial strings. I worked around this for now by editing the default config for the directory to remove presence_id from the dial string and it's working. This appears to be a bug in the parser as I was getting this error with the default configurations. Thanks, Duvid Rottenberg
