Is there any way of disabling the PAN SIP (Session Initiation Protocol) application ? My Voip provider has asked to turn SIP ALG off as they think its interfereing with the headers.
https://live.paloaltonetworks.com/docs/DOC-1216 This article says the PAN SIP app acts as a Application Layer Gateway.
Would increasing the time outs on the SIP protocol help , like stated in the article referenced in the previous post ? How do I know that is the defualt values ? When I cliked on customise , it just gave me the range of values I could provide , and not what the defualt value is.
What I would really like is to disable the Application Layer Gateway feature itself as the VOIP provider uses stun servers.
We are running the voip phones behind a NAT , so they have to get translated to reach the Internet. But the Voip provider says that SIP ALG interferes with their implementation as they use STUN servers to work around NAT , so the funtionality of a SIPALG is not needed.
And since Palo's SIP decoder acts like a ALG it seems to be curropting the packets send from the phones.
Thanks, I am using the App override feature to work around this. Are there any other application decoder that perform additional functions other than APP Identification ?
Could I submit a feature request to have option to disable any additonal features, so that I am certain that APP ID is not "modifying" the communication logic used in the network without me specifically asking it to ?
