[Asterisk-Users] R2 or E&M for E1 CAS pbx to pbx link

[Samuel Jimenez]

  Hi,

  So, u are using a new thread...  it is better if you do not change the message subject so we can trace u properly.

  Before dealing with R2 signaling which is register_signaling, you need to deal with CAS or ABCD signaling which is line_signaling and be able to establish (and drop) calls correctly.  Once this is done, R2 signaling can take place ---if fully available in *,  and R2 tones will be able to travel between switches thru the established voice channel before callers be allowed to talk.

  So, again... you need de CAS table of the far_end switch or pbx.   Get it and attach it to your post. 
  Also, if u thing u will not able to negotiate with your far en party, ask him/her in advance what signaling and start arrangement should you use.  Should tell you something like 4wire E&M, IMMediate.  This info is also crucial.


  Regards

  Sam\\\

    hi,

    thanx for the response. I just tried to work on R2 CAS but i found that the libr2 has not been implemented well and tested. I think in addition to E&M, R2 can also be used in a pbx to pbx E1 link. what do tou suggest Sam ??

    About the R2 implementation for asterisk i have seen in the list that steve has implemented 95% of that...but we dont see any release of that. any current info on R2 development??

    and Sam you are right i don't have the CAS table of the other switch. But i think i can get one. 

    help me out in this. I have to make a E1 pbx to pbx connection using CAS.

    thanks in advance

    janjua
