FORTINET VPN TUNNEL RTP AUDIO STOPS AFTER 30 SECONDS SOFTWARE
This issue is commonly present in IP SoftPhone software version 1.1.x. Note: When you use the Cisco IP SoftPhone application and more than one network interface card (NIC) is installed in the box, ensure that the box sources the correct NIC.
FORTINET VPN TUNNEL RTP AUDIO STOPS AFTER 30 SECONDS HOW TO
Note: This list explains how to verify the default router or gateway configuration on various Cisco IP phones:Ĭisco IP Phone 7910-Press Settings, select option 6, and press volume down until the Default Router field shows up.Ĭisco IP Phone 7960/40-Press Settings, select option 3, and scroll down until the Default Router field shows up.Ĭisco IP Phone 2sp+/30vip-Press **#, and then press # until gtwy= appears. IP routes on those default gateways lead to the destination networks. However, confirm these as some initial steps to follow:ĭefault gateways are configured at the end stations. This document does not cover IP routing troubleshooting. Remember that ping is a bidirectional verification. Use IP routing troubleshooting methods in order to get to the stage at which you can successfully ping Phone A from Gateway B. Therefore, the audio stream from A to B always gets lost. In some cases, Subnet B can reach Subnet A, but Subnet A cannot reach Subnet B. Once a call is established, an RTP stream that carries the audio must flow in both directions between the end stations. Therefore, signaling can reach both end stations without any problems, which allows the establishment of calls between A and B. This allows the establishment of TCP connections between the end stations (A and B) and the Cisco CallManager. This diagram shows a scenario in which this can happen: Because Real-Time Transport Protocol (RTP) streams are connectionless (transported over UDP), traffic may travel successfully in one direction but get lost in the opposite direction. In order to enable IP routing, issue this global configuration command on your Cisco IOS gateway: voice-ios-gwy(config)# ip routing Check Basic IP ReachabilityĪlways check basic IP reachability first. In other words, ensure that your router does not have the no ip routing global configuration command.

Note: Before you go any further, ensure that IP routing is enabled on your router. This default setting leads to one-way voice problems. Some Cisco IOS gateways, such as the VG200, disable IP routing by default. Ensure That IP Routing Is Enabled on the Cisco IOS Gateway and Routers This section takes a look at some of the scenarios and solutions that have been found in the field. The causes of one-way audio in IP Telephony can be varied, but the root of the problem usually involves IP routing issues. When a phone call is established from an IP station that is placed behind a VPN 3002 Hardware Client, only one of the parties receives audio (one-way communication). When a toll-bypass call is established between two Cisco gateways, only one of the parties receives audio (one-way communication). When a phone call is established from an IP station through a Cisco IOS voice gateway or router, only one of the parties receives audio (one-way communication).

This document is not restricted to specific software or hardware versions. This document is intended for personnel who are involved with IP Telephony networks and have basic knowledge of voice networks. The Cisco gateways that this document covers are Cisco IOS ® gateways and routers, Catalyst switches, and DT-24+ gateways. This document addresses some of the common issues that can occur in IP Telephony one-way audio conversations that involve Cisco gateways.
