SRG to CS1000 H323 trunks one-way speech

[dublinman]

I have an issue with one way speech between an SRG 1.5 and CS1000 450w.I have tried different codec with no result.The trunks work ok desk to desk but when I put basic rates on the SRG and point it up to the CS1000 callpilot for IVR and then to a ip phone registered off the CS1000 this is were I get the one way speech.
ANY IDEAS

Do your payload sizes match as far as the codecs go?

 

[dublinman]

Yes the payload size is 20ms both ends

Sounds like it may be an IP routing issue. If you call from IP set on the SRG to IP set on the CS 1000, is everything OK then?

 

[dublinman]

Yes no problems

Hi, fully patch your 50 with the latest. then go to Loops for the bri and you should see a drop down box with s-t t-t change this to t-t and you should now have 2way speech.
