People can't hear me but I can hear them.

I have an OBI202 configured with Anveo numbers on SP2 and SP3.  The problem is the following:

1.  A connection is made, either making or receiving a call.
2.  I can hear them.
3.  But, they can't hear me.

This system has been working for more than a year without flaw.  That is, until my lovely ISP (TW) reset my modem and I had to reconfigure everything.

Any clues??

MarkObihai:
It seems like there is a problem with your router configuration.  One way audio is usually caused by the router blocking (or impeding) communications in one direction.  This can also be caused by bad SIP ALG implementations, which is common occurrence on many home routers.  I'm jumping to conclusions, but it is possible that the new software your ISP loaded onto your router contains a SIP ALG.

Within the OBi there are a couple of settings you can enable to try and counter the router's bad behaviour:

X_DiscoverPublicAddress
X_UsePublicAddressInVia

These are located in the ITSP A/B/C etc profile for each voice service you are having problems with.

Enable them like this:

Mango:
Please try Mark's suggestion first, then mine afterward, so that we know specifically which settings solved the problem.

Service Providers >> ITSP Profile X >> SIP
ProxyServerPort: 5010
OutboundProxyPort: 5010
X_ProxyServerRedundancy: (checked)
X_DnsSrvAutoPrefix: (checked)

Voice Services >> SP2
X_UserAgentPort: 37845

37845 is a random number.  If SP2 works, you can use a different random number between 20000 and 65535 for SP3.

If the above does not work, change Service Providers >> ITSP Profile X >> SIP >> ProxyServerTransport.  It may be set to either UDP or TCP; change it from whatever it is now.

If you use OBiTALK to configure your device, you will need to use OBi Expert Configuration to make the change.

Let us know how things go.

Problem solved by resetting Obi and totally configuring it.  I did NOT use the automatic Anveo configuration, but used the generic template as suggested at https://www.anveo.com/faq.asp?code=sip_obi110
.  I also did use port 5010 rather than 5060 as suggested in the link above.

Thanks for your efforts

NOT SOLVED YET - I thought it was !

The real symptom occurs when I place a call through Obi->Anveo, then I can talk but NOT hear.

If I receive a call through Anveo->Obi then I can BOTH hear and listen.

I must be stupid, or it is not obvious, but how do you change the parameters you suggested.  I get to the menu items OK, but they are read-only.

The way I am getting to the menu item is as follows:

OBi Dashboard -> SP1 edit -> Device Coniguration ->OBi Expert Configuration -> Enter OBi Expert -> Service Providers -> ITSP Profile A SIP

   ProxyServerPort already set to 5010
   OutboundProxyPort  "      "    "    "
   X_ProxyServerRedundacy is NOT checked - but I can't change it
   X_DnsSrvAutoPrefix         "   "      "           "   "  "      "       "
   etc. with all the other settings

See attached html file for the remaining Service Providers info.
