Can any one Help me regarding E&M in CISCO by which PSTN line can use
Dear sir I am requesting you to give some time to read my problem what I feel that u can solve this thing
Now from the very beginning I am telling scenario.
We have 2 office . let give the name of that office one is A and another one is B .
Side A has 4 PSTN connection entered in to the CO port of the PABX system. I request my PBX engineer to configure the PBX system & add & E&M card. & then setup one Cisco 1751 4V it has 2 Ethernet card one is for LAN another one is for WLAN. NM is all E&M. what I did that is I connect that E&M with the PBX system. That means it is a TIE TRUNK.
In the other office that Means in Side B what I Did that is I have another PBX system but in Side B there is no Telephone lines. (PSTN). It is very important that both the office are connected through Radio Link .. & the ping time between them is 10ms/13ms/20ms.
Now my PBX engineer configure the E&M card of the PBX in side B then I connect that with my another Router which is for SIDE B this router is same like SIDE B .
Previously I did not mention that from the Radio Link is connected with the Router in both side & the LAN port is connected with the switch.
Thing is when side A want to call side B then they press 82 to get access the Router E&M Port then they Press Side B router Destination Pattern 7(I assigned that according with my PBX engineer ) then any 3 digit like 111 then it is ringing .. & both the person can talk & the voice quality is also good.
Now when the Side B people want to talk SIDE A ppl then what they do they dial 9 to get access to their router E&M Port then dial the Side A router destination Pattern like 5 (which is given by my PBX engineer.) & dial any 3 digit like 115 . then it is ringing.
Up to this much is ok .. But my problem is some where else.
That is the SIDE B people want to use the PSTN line which is connected with the PBX of Side A. one more thing I forgot to tell that the People in side A when they want to get access to PSTN or dial the PSTN network then they dial 9 to get access . then they got a dial tone which is PSTN dial tone after that they press the PSTN number.
Now when the SIDE B ppl dial 9 then they get access the dial tone of his own router which is connected with that PBX system. Then they press 5 to reach side A then usually they can press the 9 & the PSTN digit but it is not going what can be the problem . is the problem in my configuration or with the PBX system or this is the limitation in the E&M card of the router.
I am in very big problem for this reason.. so will u kindly help me for this .. & I am very glad to u that u read this with ur full passion.. & I request u to help me if u can.
