there shouldn't be anything, but if you do the place to make those changes is voip &gt;&nbsp;settings. &nbsp;you may need to enable consistent NAT or modify some of the SIP settings. &nbsp;H.323 settings should be enabled by default.<br />

i had a client who we could not get VoIP to work over the internet. &nbsp;they would not give me access to their firewall until i insisted using various means. &nbsp;once i got in, i realized they did not have h.323 enabled. &nbsp;i believe i enabled consistent NAT, but can't recall. &nbsp;i know the h.323 was key.

Thanks for the reply. I contacted ViaTalk and they gave me the following info:<br />
<br />
&quot;Sonicwall routers have more features that could cause issues for the adapter. With proper port forwarding, and the disabling of the SPI firewall (Stateful Packet Inspection) and SIP ALG (application level gateway), the adapter should work properly behind it.&quot;<br />
<br />
Any comments on their suggestions?

Is there any special configuration considerations when using a PAP2 device from ViaTalk behind a sonicawall TZ100? What is a recommended config for sonicwall with Voip traffic?

Is there any special configuration considerations when using a PAP2 device from ViaTalk behind a sonicawall TZ100? What is a recommended config for sonicwall with Voip traffic?

Sonicwall and PAP2 config

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).

Voice Over IP

The term broadband commonly refers to high-speed Internet access that is always on and faster than the traditional dial-up access. Broadband includes several high-speed transmission technologies such as digital subscriber line (DSL), cable, fiber optics, wireless (for which there is a separate topic), satellite and broadband over powerlines (BPL).
