[asterisk-biz] Virizion Interconnection

Hi all

For past week I’ve doing everything I could think of to interconnect with Verizon with no luck.

Right now our at their end we are setup with h323, at our end we use Asterisk 1.4.

When we send a call we get busy signal, finally I have contacted them and told them about the problem, and they asked me to send them exact time/date of my calls after that I’ve received this email from them.

Hi Sean,

 

See the attached call trace and see incorrect packetization timers. 

 

EXAMPLE:

 

Octet263  audioData            

--------------------------------------------------------------------------------

 ......0.  Extension bit          (0) Value is within the range of the extension root

 ........  Index                  (3) g711Ulaw64k

 ...00000  Spare                  0

 ........  g711Ulaw64k            150

 

 

Your calls are showing multiple timers that are incompatible.  (For example packetization timer of 150 ms on g711Ulaw64k and g711Alaw64k calls).  These will be rejected by our ENGINE platform.  You are sending in incompatible packetization timing on your OLC (open logical channel)'s codec list.  Our server is replying with a "normal unspecified" RELEASE COMPLETE message within milliseconds.  

 

I emphasizing that the calls are failing due to multiple incompatible packetization timing that you are sending us.  Please review for this or have your vendor review and correct.  You need to correct to the below as they are our default timers.

 

Our defaults for H.323 inbound packetization rates are as follows:

 

INP=1

G.711 Packetization 20ms

G.729A Packetization 40ms

G.729AB Packetization 40ms

G.723.1 Packetization 60ms

G.723.1a Packetization 60ms

G.726-32 Packetization  10ms

 I did some research on the net without any luck, I did came across this lists with someone else having issue with Verizon interconnection, so if any of you could help us out here it would be greatly appreciated.

Best Regards

Sean
