Dialling to 1750 E/M i/f problem

Hi all,

I have a question to you VOIP man amd experts..

I got two cisco 1750 registered undere 2 different gatekeepers, one 1750 with FXS voice card(with GK1) and the other with E&M i/f(GK2).

Recently the 1750-FXS cannot reach the extensions(behind the PBX of course) at the 1750-E&M. I believe the 1750-FXS is OK to reach the 1750-E&M because a tone is heard upon dialling, but the 1750-E&M simply cannot accept further digits(extensions) and becomes timeout later.

It seems that any 1750 registered under GK1 cannot reach individual extensions at 1750-E&M(but can can enter the PBX via the E&M i/f!!!).

Any ideas why only the 1750 with GK1 can't reach accept 1750E&M?

P.S.: All GK's are with similar config, they only differ in geographic locations.

Often times complex troubleshooting issues are best addressed in an interactive session with one of our trained technical assistance engineers. While other forum users may be able to help, it’s often difficult to do so for this type of issue.

The problem was solved after I "downgraded the router IOS to an older version, everything works fine then.

Thanks for your inputs.
