I have 1 SIP Trunk configured and working on a Mitel 3300 MCD 4.0 UR1 with the following SIP PEER PROFILE options:
SDP Options
Allow Peer To Use Multiple Active M-Lines: No
Enable Mitel Proprietary SDP: No
Force sending SDP in initial Invite message: No
Force sending SDP in initial Invite - Early Answer: Yes
NAT Keepalive: No
Prevent the Use of IP Address 0.0.0.0 in SDP Messages: Yes
Renegotiate SDP To Enforce Symmetric Codec: No
Repeat SDP Answer If Duplicate Offer Is Received: No
RTP Packetization Rate Override: No
RTP Packetization Rate: 20ms
Special handling of Offers in 2XX responses (INVITE): No
Suppress Use of SDP Inactive Media Streams: Yes
Signaling and Header Manipulation Options
Session Timer: 90
Build Contact Using Request URI Address: No
Disable Reliable Provisional Responses: Yes
Enable sending '+' for E.164 numbers: No
Ignore Incoming Loose Routing Indication: No
Use P-Asserted Identity Header: No
Use P-Preferred Identity Header: No
Use Restricted Character Set For Authentication: No
Use To Address in From Header on Outgoing Calls: No
Any way I slice these options, I'm having the same problem, which is placing a call on HOLD from the IP station (and with MOH turned on with Embedded) causes the call to get lost. It doesn't disconnect right away. The caller does not hear MOH and the IP Phone (5360) can retrieve the call but there's no one there.
If I turn off MOH, the call gets held @ the SIP provider and the caller hears the provider's music, AND the call CAN be retrieved from hold. Problem is that this scenario doesn't work well for Dynamic Extension and transfers.
Topology: 192.168.253.x = phones and 3300 (DHCP reject from 192.168.254.1 and redirected to 253.x subnet, 3300 is DHCP there) - 192.168.254.4 is gateway/proxy for SIP trunk (Edgemarc 200A), with programmed route for use of separate Sonicwall router for VLAN routing.
