 Call transfer to outside line 7200S SIP | Joined: Dec 2001 Posts: 226 Member | OP  Member Joined: Dec 2001 Posts: 226 | Greeting Inmates
I have a 7200s with SIP trunks. We are transferring calls to people at Home and on Cell phones.
Getting disconnection after awhile Intermittently. No details yet like duration of calls.
Wondering if there is an unsupervised transfer timer. ie Does the system disconnect after a certain duration | | | Re: Call transfer to outside line 7200S SIP | Joined: May 2004 Posts: 730 Member |  Member Joined: May 2004 Posts: 730 | Check MMC 501 also anything that might apply in 210. | | | Re: Call transfer to outside line 7200S SIP | Joined: Dec 2001 Posts: 226 Member | | OP Member Joined: Dec 2001 Posts: 226 | Tried adjusting CO/CO disconnect timer, it has no effect on SIP to SIP calls. Still hoping for something specific
Getting disconnected at a little over 15 minutes consistently

Session expire time 1800 seconds Also tried 180 which made no difference

Trunk reg time is 1800 seconds | | | |
