mgcp fxs to remote site g729, silence heard

[sdeltoro1]

Any ideas why on remote sites using g729 the silence is heard. on central site g711 work fine. the ccm is 4.1 and the router is 1751-v using fxs.

Try these commands:

mgcp behavior g729-variants static-pt

mgcp behavior dynamically-change-codec-pt disable

Also, you can disable the advertising of G729 annex b in the service parameters.

hth,
