PSTN Phone disconnects after on-hold for 25 seconds

[ShailendraK]

Hi all,

My PSTN phone disconnects after 25 seconds when I put it on hold from my MGCP branch router.

I don't know what other information to provide here. Please ask questions.

Thanks in advance for helping out.

Hi thanks for taking the time to reply,

The call in or out to the PSTN was having the same problem.

The issue is resolved by the foll command:

no mgcp timer receive-rtcp

as suggested by Rob.

Hi Shailendra,

Please try the following command on your gateway.

no mgcp timer receive-rtcp
