MiVB-EX Remote Retrieve Call Held by Generic SIP or Analog-FXS not working

[bojo387]

I'm trying to remotely retrieve an internal call that was put on hold by either a Generic SIP phone or the EX-Controller's FXS but fail to do so. However, I can remotely retrieve any call held by a MiNET user. The COS, SIP device capabilities, Interconnect no. are the same for my test users.

Call Hold done by MiNET - Remote Retrieve is OK by MiNET, Analog-FXS, Generic SIP
Call Hold done by Analog-FXS or Generic SIP - Remote Retrieve is NOK by MiNET, Analog-FXS, Generic SIP

The message on the MiNET phone says Not Allowed.

I simply follow the FAC<number of who placed the call on hold>.

Any suggestions on what I should check?

It's been a long time since I've had to deal with this but if I remember correctly, the analog device had to use a FAC code to actually put the call on hold so it was retrievable.

Thanks, Ralph.

The problem with the EX-Controller is that the analog interfaces (FXS and FXO) are converted to SIP so some ONS functions, I understand, work differently. I will try putting the call on hold via FAC when I'm back at the office but I recall it not working... as soon as I hit the flash key, the call already gets put on hold. Another flash retrieves the call. In hold - retrieve though, I can also use the retrieve FAC on the same extension that initiated the hold.

I'll dig up more.

I believe, if I remember correctly, a single flash is a soft hold. Basically it's a transfer hold. 
Do a single flash then the FAC.  That should put it in a hard hold.

I've opened a ticket with Mitel so hopefully, I get a resolution.

For the FXS, as soon as I hit flash, the call is put on hold. Dialing the hold FAC after a flash does nothing....

I'll keep this thread updated once I hear back from Mitel.

As you suspected, the Analog-FXS (EX-Controller) isn't doing a full hold as the flash + FAC doesn't work. Therefore, the held call cannot be retrieved remotely.

I am now waiting for Mitel to fix the issue. It looks like a SIP issue to me in general since the EX-FXS, Generic SIP and Analog-AG are affected. (These are all SIP anyway).
