Hi, I have configured a Panasonic KX-HDV230, Panasonic KX-HDV130, an Ekiga softphone, and a SIP trunk from Sipgate using the PJSIP Wizard.
I can make calls between the phones/softphone fine, including putting calls on hold, and transferring calls.
I can make calls to/from the trunk to/from the phones with audio, however I am getting some strange behavior.
When making calls between a trunk and a SIP phone (e.g. using a mobile phone), if either side hangs up, the call will still be active at the other side. (e.g. if mobile hangs up, SIP phone is still showing an active call, and “core show channels” is showing a call taking place, or if SIP phone hangs up, the mobile is still showing a call taking place).
Also if I try to put a call from the trunk on hold (or try to transfer a call), it immediately hangs up.
The phone will say “Line On Hold” briefly on the screen, and beep as normal, but then the call is ended.
Below is my trunk configuration:
[sipgate] type = wizard transport = transport-udp remote_hosts = sipconnect.sipgate.co.uk sends_registrations = yes sends_auth = yes outbound_auth/username = SIPID outbound_auth/password = SIPPASSWORD endpoint/context = from-external aor/qualify_frequency = 30 aor/remove_existing = yes endpoint/allow = !all,ulaw,alaw endpoint/from_user = SIPID endpoint/from_domain = sipconnect.sipgate.co.uk endpoint/dtmf_mode = rfc4733 endpoint/rewrite_contact = yes endpoint/timers = yes endpoint/rtp_symmetric = yes endpoint/force_rport = yes
Below is a SIP trace from a call where I try to put it on hold and it disconnects:
NUMBERMOBILE = My mobile number removed
NUMBERTRUNK = Incoming trunk number removed
SIPID = Username for trunk removed
MYIP = My external ISP IP
10.0.0.16 = Asterisk PBX
10.0.0.30 = Panasonic KX-HDV230
