8.17 SIP VIRTUAL MOBILE EXTENSION (VMEX)
Description
SIP gives us the opportunity to provide a truly integrated and cost effective mobile extension
solution. The closer integration lets the mobile users to use the mobile exactly as they are used
to.
The goal have been to integrate the mobile phone even further with the PBX (out-band
signaling) and add a more cost effective solution for bigger systems (recursing diversion). The
out-band signaling is mandatory. Recursing diversion is not required in smaller solutions, but
still more cost effective. In a bigger solution, more then 20-30 MEX users, it is needed to
compete with Aastra, Cisco and various hosted solutions, including the hosted solution we sell.
Out-band signaling makes it a truly transparent solution. The user places an outgoing call
exactly as he is used to and it works on any cell phone. This means that the user can use
speed dials and do not need to have any special phone or application installed in the phone.
Also the use of DISA, which is considered too complicated by many users, will be obsolete.
Operation
1. Incoming call (from PSTN to MEX)
TDC uses a prefix on the To tag and From/Contact tag. These prefixes are trunk
based and should be added to the mobile extension section of pgm 133.
1. The Public user calls 084707405 (LIP 105) and an Invite [A] is sent to iPECS.
2. LIP 105 has MEX and the call should be routed to MEX 105.
We now need to add two prefixes to the outgoing Invite [B] and they are
described below.
[A] Incoming Invite
From: < sip:[email protected]:5060;user=phone >;
tag=1399855756
To: < sip:[email protected]:5060;user=phone >
Contact: < sip:[email protected]:5060;transport=udp >
[B] Outgoing Invite
To: < sip:[email protected] >
From: < sip:[email protected] >;tag=61D3F1B4-1ACC
Contact: < sip:[email protected]:5060 >
The incoming and the outgoing Invite looks as they do today except for two
prefix that are added to the outgoing invite.
