Hi Carlos

It could help if you can get a trace of the call transfer from Nortel to SIP extension on the Asterisk (1303), if no way to get from Nortel get from Asterisk.
I guest operator try to make a bind call transfer, without wait complete DR2 signalling exchange at least minimal time exchange DR2 signalling between Nortel and Asterisk is about 5 sec.

Hi Carlos

How about to perform the call transfer operation (screened and unscreened) and trace the communication it will better on Nortel PBX side, in order to know which point is causing call transfer failure.
By the way these kind of features is complicated to handler on interconnected system, I just mean is no easy way for check intersystem resource state, as other than inband tones, mainly PBX system interconnect to others system by trunk resource and communication between system are handler by Trunk to Trunk PBX system control operation, PBX only use remote state (Busy, Congestion, etc.) for management own Trunk to Trunk resource operation.
Just in case of these kind of scenario it can be done through E1 (DR2 MFCR2 or DTMF) or ISDN PRI QSIG, lastone is more convenience because it cover more supplementary services than DR2 as; Completion of Calls to BusySubscriber (CCBS), Call Hold (HOLD)—by ISDN etc.

Hello All,
I’m having issues with asterisk 1.8.4 dropping calls during transfer, and
transfer to park extension. We’re using polycom soundpoint IP 650. when the
park button is hit the response is “i’m sorry not an extension” at the same
time number 7 appers on the lcd.

Thanks in advance.

Hi,

Is it possible to transfer a call in Asterisk SLA (shared line appearance) e.g., call comes in via SLATrunk, it’s answered, and transferred to an outside number?

Thanks,
Matt

Ok I now have the basics for dynamic parking working but for some reason
when a caller calls in and is parked with a transfer the return call dials
the sip peer of the caller and not hte peer of the last party that parked
the call. Anyone have any ideas on this? Also when a call is transfered to
a parking space. the caller hears the space number. How can I stop that as
well?

Thanks

Bryant
