How DECT 9371 Single Can Enhance Your Voice Communication with High Def Sound and Color Display



About the size of a telephone, the cost-effective MC1000 Deskset allows remote control access to the basic functions of a single base station, repeater or radio in a conventional system. This compact yet powerful deskset allows 10 units to operate in parallel.and offers hands-free operation.

New interop tweak /single-audio-descriptionCalls with OPTIONAL media encryption are usually offered with SDP containing 2 media descriptions.One for RTP/SAVP and one for RTP/AVP.Some equipment cannot deal with multiple audio descriptions.With this option only one audio description will be sent.RTP/SAVP or RTP/AVP.


If SDP answer is received with more than one Audio codec we take the top-most codec as the selected one.We send and receive this codec.But the remote endpoint may send the other codec.Our endpoints can only send/receive one codec at a time.In order to pinpoint the selected codec to only one, we now send a re-INVITE with a single-coder-offer right after negotiation (RFC-4317).


In case of SIP over stream-oriented transports, SIP stack must read incoming stream and turn received data into single messages.If remote side sends single CRLF packets between real messages the following SIP message was discarded.Found on interworking with Pexip Infinity Conferencing Platform.


XCAPI gives us re-INVITE with SDP offer containing a single RTP/AVP description.We must return SDP answer with also a single RTP/AVP description.Not SDP answer with 2 m-lines (RTP/SAVP and RTP/AVP).


Show full remote display info and phone number on incoming calls. Remote display name is displayed on multiple display lines if display name and number do not fit together into single display line.


REGISTER requests with different Call-ID are not refresh for existing registrations.Even if Contact-URI is the same as in earlier REGISTER requests.RFC-3261 "10.2.4 Refreshing Bindings" says:A UA SHOULD use the same Call-ID for all registrations during a single boot cycle.


Follow-up to fix #16000 - SIP: Fix for asymmetric codec problemIf SDP answer is received with more than one audio codec we take the top-most codec as the selected one.We send and receive this codec.But the remote endpoint may send other codec.Our endpoints can only send/receive one codec at a time.In order to pinpoint the selected codec to only one, we now send a re-INVITE with a single-coder-offer right after negotiation (RFC-4317).In case of late Offer/Answer exchange (200/OK and ACK) this pinpointing was missing.From now on pinpointing is also done here.


PolycomSoundStationIP uses different Call-ID on registration refresh.This is against RFC-3261 (A UA SHOULD use the same Call-ID for all registrations during a single boot cycle).SIP stack takes this as new additional registration.Old registration is not refreshed and will time-out soon.Interoperability issue with PolycomSoundStationIP.Inbound INVITEs are associated with old registration due to identical Contact-URI.When old registration times-out calls are dropped.


the USB headset table was a single xml structure containing the command descriptions of all supported devices. To overcome some xml decoder limit the table is now splitted in separate per device structures. 2ff7e9595c
