Yeah .. what I meant was ip address to be zero ( not the port ). Setting the ip address as zero is not a standard solution but still you can still find it is used widely. By setting the ip address to zero, bascially you will not be getting the RTCP packets from the phoneB. Going by the philosophy "Be strict while delivering, but liberal while accepting", a=sendonly *should* be well enough to put phoneB on hold. (phoneB *must* also support RFC 3264). You may need not set the ip address to 0.0.0.0. a=inactive is used when both the parties prefer not to send media and thus making the media inactive. Hope this helps, Somesh

If you make your port as 0, this will also result in an Hold condition. There are two approaches used: (1) Make port as zero (2) Include a=sendonly attribute Somesh -----Original Message----- From: sip-implementors-boun...@lists.cs.columbia.edu <http://in.mc88.mail.yahoo.com/mc/compose?to=sip-implementors-boun...@lists.cs.columbia.edu> [mailto:sip-implementors-boun...@lists.cs.columbia.edu <http://in.mc88.mail.yahoo.com/mc/compose?to=sip-implementors-boun...@lists.cs.columbia.edu> ] On Behalf Of ext friend friend Sent: Friday, July 03, 2009 5:48 PM To: sip-implementors@lists.cs.columbia.edu <http://in.mc88.mail.yahoo.com/mc/compose?to=sip-implement...@lists.cs.columbia.edu> ; shamik.s...@wipro.com <http://in.mc88.mail.yahoo.com/mc/compose?to=shamik.s...@wipro.com> Subject: Re: [Sip-implementors] Doubt in RTP(Media port) Thanks for your Information Regards, vijay --- On Fri, 3/7/09, shamik.s...@wipro.com <http://in.mc88.mail.yahoo.com/mc/compose?to=shamik.s...@wipro.com> <shamik.s...@wipro.com <http://in.mc88.mail.yahoo.com/mc/compose?to=shamik.s...@wipro.com> > wrote: From: shamik.s...@wipro.com <http://in.mc88.mail.yahoo.com/mc/compose?to=shamik.s...@wipro.com> <shamik.s...@wipro.com <http://in.mc88.mail.yahoo.com/mc/compose?to=shamik.s...@wipro.com> > Subject: Re: [Sip-implementors] Doubt in RTP(Media port) To: sip_qu...@yahoo.co.in <http://in.mc88.mail.yahoo.com/mc/compose?to=sip_qu...@yahoo.co.in> , sip-implementors@lists.cs.columbia.edu <http://in.mc88.mail.yahoo.com/mc/compose?to=sip-implement...@lists.cs.columbia.edu> Date: Friday, 3 July, 2009, 5:05 PM During call hold just change the attribute to inactive don't change the media port.
