MiVoice SIP Trunk Issues

MiVoice SIP Trunk Issues

MiVoice SIP Trunk Issues

I have an up to date Mitel VOIP system using SIP trunks that drops calls at the 15 minute interval due to the service provider sending new port requests and our phones move to the new port but the siperator (SIP Provider) device doesnt.

RE: MiVoice SIP Trunk Issues

Seems like nothing you can do so just take it one step at a time.
Sounds like you already have the packet capture that includes the problem so send that to the service provider and ask for advice.
If their response is, and likely it will be, that this is a normal standard procedure, then take that to Siperator support.
Whenever there is anything in the middle of a communication channel that fails to support the endpoints, then you advise the customer to replace it.
You might just sell an MBG.

RE: MiVoice SIP Trunk Issues


I've had that problem before, in my case as usual it was a Firewall setting, I can't remember the setting as I passed it to the Firewall chaps. Its something to do with Sip Provider sending a re-invite. Look at TCP or UDP Timers in Firewall. Oh and I think Sip ALG should be disabled.
