Hi, I've found that neither Michael Manousos patch nor ztdummy driver do not fix musiconhold sound interruption problem up to acceptable quality level. Sound is choppy here anyway. It is my understanding (please correct me if I'm wrong) that if I have a Digium card in my asterisk machine, these problems should be gone 'cause those cards provide some reliable timing. So I have no choice and wish to buy a cheapest Digium card just for timing. I have no PSTN ports, it's pure voip environment here. So my question is whether any Digium card would be ok or I have to buy some specific card? I'm looking at X100P card as it is the cheapest one. Would it be enough? Thank you. Michael
With the musiconhold and SIP-SIP call it turnes out that you need to disable silence supporesion on your phones/gateways since the timing is taken from the coming stream (but only for musiconhold AFAIK) regards Martin On Tue, 14 Oct 2003, Michael Ulitskiy wrote:> Hi, > > I've found that neither Michael Manousos patch nor ztdummy driver > do not fix musiconhold sound interruption problem up to acceptable quality > level.

No. I also run machines with pure VoIP and there is not a single problem with music on hold. I don't think an X100P card will help. Anything you gain from the ztdummy driver will be the same as what you can gain from an X100P, FWIW the card is just a $10 winmodem.> -----Original Message----- > From: asterisk-users-admin@lists.digium.com [mailto:asterisk-users- > admin@lists.digium.com] On Behalf Of Michael Ulitskiy > Sent: Tuesday, October 14, 2003 4:46 PM > To: asterisk-users@lists.digium.com > Subject: [Asterisk-Users] Digium cards just for timing > > Hi, > > I've found that neither Michael Manousos patch nor ztdummy driver > do not fix musiconhold sound interruption problem up to acceptablequality> level.

Michael --------------------- Michael, Have you tried zaprtc from http://www.junghanns.net/asterisk ? It seems to be working here on a 'SIP only' configuration without any problems. Music on hold sounds perfect. -Nathan

[Asterisk-Users] Digium cards just for timing - moden cards?
I think the X101P uses an Ambient/Intel HAM 56K modem chip. The older X100 is based on Motorola. Any authoritative answers? Andrew Kohlsmith wrote:>>Is that why there is an X100P and an X101P?

most probably use tjnetworks chips, www.tjnet.com to be specific: http://www.tjnet.com/chips/tiger320.htm I am not sure though:) ----- Original Message ----- From: "Leo Ann Boon" <leo@innovax.com.sg> To: <asterisk-users@lists.digium.com> Sent: Wednesday, October 15, 2003 6:09 AM Subject: Re: [Asterisk-Users] Digium cards just for timing - moden cards?> I think the X101P uses an Ambient/Intel HAM 56K modem chip.
