A couple of things to check/answer that should point you in the direction of the corrective actions.
1. Is Data and Voice over IP traffic going over this FR link? 2. If 1 is yes, then, has it always been this way? 3. If 2 is no, then, what has changed in terms of traffic across the link? You might need to look into implementing LLQ traffic shaping to manage/protect the time-sensitive Voice traffic. 4. If 2 is yes, then A) check to see if your configuration on the routers has changed in regards to the traffic queuing mechanism you have in place B) check your Serial Interface stats to see if there are CRC errors or other types of circuit problems, or check the Frame Relay stats for FECN/BECN issues, etc. HTH's Mark -----Original Message----- From: K A [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 25, 2003 10:05 PM To: [EMAIL PROTECTED] Subject: Voice degradation problem in Cisco VoIP network [7:63823] Hi, I am getting voice degradation problem b/w our two sites. Both of these 2 sites are connected using Framerelay with a very good bandwidth. Routers on both sides are 2600 Series with VoIP cards. Calls from one PBX are forwarded to my 2600 router and then it will transmit the VoIP packets to next 2600 Series which will get it back to the destination. The problem is the voice quality which is really terrible. Can you please kindly let me know what are the factors that I should work over now. I am new to Cisco Ip Telephony. So please let me know the basic points or factors on which I should base my research now. I will do my hardwork to resolve it if you guys can give me the basic points to work on. I will really appreciate your co-operation. Thanks alot in advance.
