 SL2100 dropping calls | Joined: Nov 2001 Posts: 413 Member | OP  Member Joined: Nov 2001 Posts: 413 | Having a problem, intermittent , with off site VoIP phones at different locations. Using SIP trunks, inbound call rings, go off hook and call is not there, receive a error tone. No problem at the host location. Any setting I can check in programming or a possible router issue at the switch side?

This worked for me. | | | Re: SL2100 dropping calls | Joined: May 2002 Posts: 4,014 Moderator-Avaya, Polycom | | Moderator-Avaya, Polycom Joined: May 2002 Posts: 4,014 | Are you using a POE ROUTER | | | Re: SL2100 dropping calls | Joined: Sep 2004 Posts: 3,956 Member |  Member Joined: Sep 2004 Posts: 3,956 | Changing 15-05-47 and 48 normally will fix this as sonnym suggested. However, best practice is to get the timer increased on the router/firewall causing this issue. For a few phones this is no biggie, bit deployments you are using bandwidth for no good reason. | | | Re: SL2100 dropping calls | Joined: Sep 2004 Posts: 3,956 Member | | Member Joined: Sep 2004 Posts: 3,956 | Changing 15-05-47 and 48 normally will fix this as sonnym suggested.
