Dear Kamailio'ns,
I am
working on kamailio Server (V 4.0) installed on Ubuntu 12.04 system.
Currently i am trying file transfer feature using IMSDroid SIP clients.
file transferring is fine between two IMSDroid clients but at the
receiving end (file recipient) i cont see the sender identity/ sender
name. it is just displaying as 'null' (Screen shot is attached). But the
full file is transferring to destination address without any problem.
I
have configured MSRP module related script in my kamailio configuration
file (find the attachment). but i guess it is not invoking anyway when
file transferring and the file transferring is negotiating
client-to-client basis.
And also find Sip capture of file transfer (ngrep based) for better understanding.
What
could be the problem? Why at the file recipient side it is not
displaying sender's identity (instead it is 'null')? how can i resolve
this issue?
Anyone please help me in resolving this issue.
Any help will greatly appreciate.
