Have you set the gateway in sipx to "Use Dummy RTP payload" and
registered to one of their red headed stepchildren POP's?
Yes, I did try that, but no luck. Not sure if the sip spec says
anything about a keepalive during a call.
I say stepchild, because they seem to treat all pop's differently or
with favoritism. I'm sure those POP's got what they deserve though.

Does anyone know of a sipx rtp "keepalive" setting during voicemail?
I just wanted to share this experience for anyone in the future
having this problem:
02:37:02 PM *[Gerald Drouillard]* Yes, and the voicemail
message is capped at exactly 1 min everytime with the 2 dids
on this account.
02:37:57 PM *[Gerald Drouillard]* Calling in through a
different ITSP to the same extension does not have that problem.
02:38:31 PM *[Albert]* I see. Please hold on a moment.
02:38:41 PM *[Gerald Drouillard]* Under this same account the
other subaccount does not have the problem
02:40:22 PM *[Albert]* You're using the same PBX and the same
network?
02:41:04 PM *[Gerald Drouillard]* Same version of pbx
different location
02:41:22 PM *[Gerald Drouillard]* I actually have 2 other
locations working fine
02:42:33 PM *[Albert]* Ok. Let me check your settings one more
time.
02:46:44 PM *[Gerald Drouillard]* I see a rate limiting entry
on the firewall. I disabled and will try again.
02:48:41 PM *[Albert]* Sure let me know if that helps.
02:49:18 PM *[Gerald Drouillard]* Nope.
02:52:31 PM *[Gerald Drouillard]* The "bye" does come from
your system.
02:53:43 PM *[Albert]* Ok, hold on a moment.
02:55:22 PM *[Gerald Drouillard]* Is there a "hang up on 1 min
of silence coming from my pbx" setting on your side?
02:59:11 PM *[Gerald Drouillard]* I am rebooting the system
now to disable one other iptables rule.
02:59:59 PM *[Gerald Drouillard]* Keep in mind though it does
work coming in from another ITSP
03:00:57 PM *[Albert]* Yes, we understand. We are currently
reviewing the trace. Please make any test that you try
convenient and let us know if that helps.
03:09:22 PM *[Albert]* Gerald, can you let me know if the call
that goes to your voicemail is put in hold or something like that.
03:10:26 PM *[Albert]* Because we don't have any timeout
setting if the call remain in silence during a period of time.
03:14:22 PM *[Albert]* Also notice that at the moment our
server have a timeout of 60 seconds if we don't receive any
RTP packages. In that case if your system/device doesn't send
any RTP package during that time the call is ended.
03:15:26 PM *[Gerald Drouillard]* I doubt it, the trace shows
ringing, then IVR.
03:15:54 PM *[Gerald Drouillard]* When leaving a voicemail
over 60 sec?
03:16:27 PM *[Albert]* Gerald can you please make a test using
our newyork or Los Angeles, we have that setting to 15 minutes
in those servers.
03:17:17 PM *[Gerald Drouillard]* ok. Do I have to switch the
subaccount setting or can I just log into newyork?
03:18:06 PM *[Albert]* You need to change the server in your
system and also change the Point of Presence in the DID number.
03:21:32 PM *[Albert]* Gerald, once you change those settings,
please test again.
03:22:28 PM *[Gerald Drouillard]* The settings are changed.
The pbx is logging into newyork
03:22:44 PM *[Gerald Drouillard]* I'll make the call now
03:22:50 PM *[Albert]* Ok. Sure.
03:25:45 PM *[Gerald Drouillard]* That seems to be working.
Got past 1 min
03:25:59 PM *[Gerald Drouillard]* What pop's have the 60 sec rule?
03:27:00 PM *[Albert]* Only Newyork and los Angeles have a
rule to 15 minutes. For the other servers is set to 60 seconds.
03:28:10 PM *[Albert]* What seems to be happening is that the
device stops sending RTP packages when enters to voicemail.
Please try to find a settings that avoids this behavior and
that issue should not occur.
03:28:57 PM *[Gerald Drouillard]* Why would it send RTP if it
does not have to send anything in vm?
03:29:11 PM *[Albert]* In order to keep the connection alive.
03:29:40 PM *[Albert]* I can also suggest that you perform a
firmware update to see if that helps.
03:30:16 PM *[Gerald Drouillard]* All systems are up to date.
03:30:36 PM *[Albert]* Please notice, that this is a security
measure in order to avoid the calls keep connected when the
device is not sending any information.
03:31:13 PM *[Gerald Drouillard]* There is a keep alive
setting that is set to none at the moment. I am guessing that
needs to be RTP for you?
03:33:36 PM *[Albert]* That settings usually works for the
registration.
03:34:28 PM *[Gerald Drouillard]* I don't think there is a
setting during voicemail to "keepalive"
03:34:32 PM *[Albert]* The keep alive setting, it's to prevent
a router from closing it's NAT External port.
03:35:06 PM *[Albert]* In that case Gerald, I can suggest that
you use our Newyork or Los Angeles server for the meantime.
03:35:35 PM *[Gerald Drouillard]* There is a NAT setting in
voip.ms <http://voip.ms>. Would turning that off work?
03:36:56 PM *[Albert]* No, that would not work. Please notice
that you need to find any setting related with the RTP packages.
