CallParking issue

Dear all,

i’ve configured Asterisk 11 and everything works well except the call parking.

features.conf

[general]
parkext => 700
parkpos => 701-750
context => parkedcalls
findslot => next

In the dialplan i included the context parkedcalls.

When i try to transfer a call to 700 it appears the following error:

[Nov 29 21:16:08] WARNING[2069][C-00000000]: chan_sip.c:9810 process_sdp: Ignoring video stream offer because port number is zero

What can cause the problem in the call parking? There is an error in the configuration?
Do you have any suggest on what is the best way to configure the call parking?

Thanks and best regards,
Davide

There is not enough information to establish why the parking failed. You will need to turn up debugging until a reason becomes apparent, and/or provide details of your configuration and the state of the parking lot immediately before the failure.

Dear David,

can you suggest me what is the best way to configure CallParking?

Thanks,
Davide

As in the sample configuration file, unless your particular requirements are incompatible.
