[Freeswitch-users] Problems with recorded messages cutting off at 60 seconds involving remote SDP

[Andy Ayers]

Hi,

 

I have a weird problem where on certain calls when someone tries to leave a
recorded message the call hangs up exactly 60 seconds after the start of the
recording. The recordFile is sending the stream to icecast using a shout:
address in MP3 format.

 

I've done a line by line compare of a successful call and one where the
recording fails and the issue seems to be with the remote SDP. 

 

RECORDING SUCCEEDS WHEN SDP IS..

 

v=0

o=root 1060 1060 IN IP4 77.240.60.33

s=session

c=IN IP4 77.240.60.33

t=0 0

m=audio 13850 RTP/AVP 8 0 3 97 7 110 18 101

a=rtpmap:8 PCMA/8000

a=rtpmap:0 PCMU/8000

a=rtpmap:3 GSM/8000

a=rtpmap:97 iLBC/8000

a=fmtp:97 mode=30

a=rtpmap:7 LPC/8000

a=rtpmap:110 speex/8000

a=rtpmap:18 G729/8000

a=fmtp:18 annexb=no

a=rtpmap:101 telephone-event/8000

a=fmtp:101 0-16

a=silenceSupp:off - - - -

a=ptime:20

 

RECORDING CUTS OFF AFTER 60 SECS WHEN SDP IS..

 

v=0

o=voip 302847118 302847118 IN IP4 77.240.60.4

s=voip

c=IN IP4 77.240.60.4

t=0 0

m=audio 13622 RTP/AVP 8 0 3 97 7 110 5 10 18 112 111 101

a=rtpmap:8 PCMA/8000

a=rtpmap:0 PCMU/8000

a=rtpmap:3 GSM/8000

a=rtpmap:97 iLBC/8000

a=fmtp:97 mode=30

a=rtpmap:7 LPC/8000

a=rtpmap:110 speex/8000

a=rtpmap:5 DVI4/8000

a=rtpmap:10 L16/8000

a=rtpmap:18 G729/8000

a=fmtp:18 annexb=no

a=rtpmap:112 AAL2-G726-32/8000

a=rtpmap:111 G726-32/8000

a=rtpmap:101 telephone-event/8000

a=fmtp:101 0-16

a=silenceSupp:off - - - -

a=ptime:20

 

Can anyone tell me the significance of the o=voip, s=voip as opposed to
o=root,s=session? Is this likely to be the cause of the problem and any idea
how I fix it?

 

Many thanks as always

Andy Ayers
