[Asterisk-Users] Help needed!

[Han Ben Lee]

hi all


i have asterisk on a TE410P card running on 2 E1s. E1(a) and E1(b)

Following is the call flows

1.user call from POTS to E1(a) 
2. asterisk will authentic user ANI and once authentic is clear it will play DTMF A tone
3. user key in destination number
4. asterisk uses LCR to find which Telco is the cheapest
4. asterisk pick up E1(b) and dial a local Telco gateway number
5. waits for DTMF A from Telco and send the destination number to Telco
6. asterisk connects user and destination user

user-->POTS-->E1(a)-->asterisk-->E1(b)-->E1-->Telco-->destination

the only problem with the above flow is, when E1(b) calling Telco E1. two things happen frequently
1. connection takes more than 10 secs
2. not all calls are successful

appreciate if any one has done this before and can assist.

willing to outsource if anyone has the solutions
